A downloadable game for Windows, macOS, and Linux

Fragments of Euclid is a game about exploring and solving puzzle in a mind-bending environment inspired by M.C. Escher. Enjoy the peaceful mood while trying to understand this strangely connected world.

The game is about 45 minutes long and save your progress. I want to add more content to the game in the future. With new mechanics, puzzle, more story ...

If the graphic style is too strong for your confort, you can switch it in the option menu.

Updates : 1.1 : add a checkpoint and rename another to improve one of the challenge. 1.4 : Rework of almost each puzzle to be a bit less frustrating and hint in the correct direction. 1.4c : Add option to change the Field of View between 60 and 90 degrees.

The game is based upon the short prototype "Non Euclidean Room" that I made during a Ludum Dare. You can play it there : nusan.itch.io/non-euclidean-room

this game is absolutely awesome and that to be continued gave me hope for another game like this

I really enjoyed at this, with that gravity, puzzles and more. Hope you will add more stuff and levels :D

Amazing game! Great concept and clever puzzles! I only have one little suggestion, could the camera angle be a little wider? I often felt like I couldn't see enough of the space at once...

I hope that you'll work more on this great game!

Thank you, I'm glad you liked the game! You can change the camera angle in the options if you want to.

Great demo, fun puzzle solving and lot of potential

The paper-made background is amazing, keep it up👍

This is fantastic!  I love a good puzzle game, and I especially love the non-euclidean geometry stuff happening!  I am also really impressed by the look of the game, it really carries Escher's style.  


Amazing game, nothing wrong with it. Fun to play! :)

I just paid 5$ for the game but when i try to run it nothing happens and i am very confused
*Edit* my download initially was just funny i re-downloaded the zip and extracted it and it worked perfectly, the dev was very helpful on twitter 10/10


masterpiece. I'd definately pay for an expanded version.

This game, is pure gold.

What would be the age rating for this game?

This game is suited for every age, but might be a bit difficult to understand for a young child.

I'm hoping that you are still working on this absolute masterpiece good sir.

will you add a level maker? It would be really nice to experiment with non-euclidean space

I love puzzle games and played a lot of them, but this one is quite special. Really good level design and mechanics and physics. Especially the "dropping cubes on the floor to use them as a staircase in other perspective" is pretty neat. Compared to Etherborn (finished it yesterday) or games like Bridge or Antichamber, this is easily my favourite and one of the best designed I played on itch so far. Hope to see more of your work and from this game!

Seeing the character model for the first time scared me, but as I kept looking at at its a really neat design.


The level design is really good. Sent you money for this ;)

I love this game!

good game but damn this gave me a headache

what a great time! absolutely looking forward to more of your work

NuSan, (if you're reading this) would you be able to post the code in a git repo? I'm very curious as to how you handle the odd physics, and I would love to be able to check out your code! 

Also, this is by far the coolest non-euclidean game I've seen so far! 

:o ♥

Great game!


Your game still is so fun to play!

Hoping for more soon


I'm still hoping you'll develop this into a full game. I'll pay you! With...

*searches pockets*

...money! I'll pay real cashmoneypounds for more of this.


This game is awesome! I never saw something similar.

Thanks for this great game! If you could add more filter would be great.

Very cool! Thanks for this game!

This is a wonderful game, and the song in the secret place is really nice. Sad it's not in with the rest of the soundtrack, it'd be nice to jam out to.

what secret place?

Edit:  I looked it on internet. Whoah, I can't believe I didn't find this.

It's the old game, the oldest one, from when it wasn't called fragments of euclid. NuSan was testing the teleportation, in FoE apparently he added the rotation of the view and with it, so much more to do in the game than just activate cirlces. That's an idea @NuSan you could make a sequel in which the game isn't a puzzle game about activating stuff, but a game with a story that unravels in this weird impossible game. For example it could be set after you meet Euclid. He tells you that you are in his world. A world were geometry isn't bound to the laws of nature and he could create new more interesting things. He tells you that he was training you. Training you to navigate this world and save it from an invading force. xd


I'm glad you liked the game! The story you imagined is in fact close to what I wanted to put in the next episode. You learn more about Euclid and help him through new mechanics. Unfortunately after working several month on a new episode, the project is in halt for the moment I hope to revives it one day and show you all the cool things I added.

I'm so happy to hear that you're working on a new episode.

I'm trying to make a game inspired in yours too, and I can understand how hard it is to make the game while studying/working/doing other stuff. So don't worry, take your time. I hope you get to finish it soon <3

But don't feel pushed, only program if you feel like it, it is the love the programmer and designer puts into the game that makes it so good. 


Thank you for playing the game! The song from the secret place is not it the soundtrack as it was made by me for the original prototype during Ludum Dare, and not by the composer of the other tracks. If you like it, you can find it here: http://lezanu.fr/LD37/NonsEuclidianRoom.ogg


My brain expresses gratitude :)

Alse it wants to show the game to my friends.

Just finished the game and loved it. Great aesthetic and nice story line to keep me motivated.  The nausea thing is interesting - not complaining - just feels weird shifting perspective so much, it's a challenge for the brain/inner ear.

Thanks for the experience!


it really make me feel dizzy but still its a really nice game

 but still

I found the secret place! On my second time through, that is. I had fun with it, and the puzzles were very intuitive the second time around. Also. the names are helpful hints.
OH! And are the gameplay mechanics the same as Portal's, where through each doorway is actually an identical map, connected on a different point? If so, how many alternate maps are going at once? Is it just two? Or is it only one, using some other mechanic?

pretty sure its just 1 map


It is one single map. The doors teleport you and change your orientation. That way, if you're inside a map that is the inside of a cube, you can have like six rooms in a single actual room. 

Hi there! Beautiful interesting game, do you have any interest in publishing it on steam? If you are let me know, I work for a publisher and definitely interested in working together. If you would like to talk email me at: deana@sedoc.net 

The game seems awesome for what little I played of it.  I wold've liked to have played more but sadly this one triggered heavy nausea, even when I adjusted the graphics.


I'm really sorry for that, several people reported nausea while playing, but I'm not sure how to help with that. I put an adjustable "field of view" and you can change the "stroke" effect for something less violent. Maybe it's linked to all the bright white on the screen, so lowering brightness may help. I may add an "inverted color" mode in the future, so the screen would be mostly black, or even let the player choose the color scheme. Thank you for your feedback.

Hello! Just played the game and found it amazing. Original, interesting, actually "skill-based" and founded on the imaginary of the great Escher. Very well done!

I just want to point out that I may have found a little "bug", or maybe exploit is the right word. When you have a cube picked up, while walking, if you drop the cube and then jump twice (in a fast sequence) you'll actually jump higher than just putting the cube on the ground and using it as a step. Probably because the second jump starts while the character is at the peak of the first one. By the way, I found this late in the game while playing "Meeting", so I don't know if it can be exploited to skip some levels, but I know that in "Run" you can use it to jump over the closed door without having to do the normal procedure. 

you can actually  step on the cube jump pick up the cube and use it as the " double jump" you can skip some things in the game ,but there are better ways to skip....the whole game.., lel     ( in the video below i use the normal double jumb and the extended)

Thank for the report, I saw your speedruns and was really impressed. I always find glitches and unintended mechanics really interesting. So I'm often on the fence about removing them from the game. I even found some useful skips before release, but decided to let them as it's like hidden secrets that speedrunners only would find. Usually I would want to remove things that players can stumble upon during regular gameplay, or that completely destroy the game (like when you go through the ground directly to the finish line). I think this double jump would rarely happen by mistake, so it can stay for now. Thank you for your interest in the game, let me know if you find anything else interesting!

yeah the "double jump" is great .i would also leave it in the game

i have made a little video with some thing that i have found in the game .But the video isnt online right now cause i have to upload it.i will post the link when done

there it is

Nice ! My game is sooo broken it seems :) the glitch where you just go through walls seems the worse and that it could be found by accident by an innocent first time player. The multiple jump by grabbing the cube again and again is super impressive. Thank for your video, it made my day !

i dont think people playing the first time will find any of these glitches, the wall glitch has to be verry precise. sorry for making it seem like its broken :D

This is definitely cool game concept! Kudos to M.C. Escher.

A little short game though, but acceptable for a free game. I do consider giving some support to get more of this.

Special thanks for making this to run on Linux. I probably would not even tried the game without option to install on Linux.

Looking forward to see and play more.

I could not stop until the end! Thank you for this piece of art.

cool game.But you should fix the glitch where u can go into walls

u cant really see it in this video but ,there is a way  to glitch into the walls(some not all).if you want i can make a video to show

edit: i have found a way to glitch into all walls that have  enough space
