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.

Update 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 more accessible and hint in the correct direction.

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

Woooah. This game was amazing!

At first I wasn't quite sure what I was doing but after a while I got a hang of it and it was so enjoyable. The audio was really good. The graphics looked really good and they were probably the reason I downloaded this. It reminded me a little bit of Portal too which also attracted me to it. 

I really liked the way there were 4 places to go to with their own sets of puzzles to go through. I was kind of weirded out at how we are literally a tentacle monster/ jellyfish but it was really neat how we weren't just a head or invisible and that we could actually see ourselves. I also found the transfering from one puzzle to another really clever, even though I didn't quite understand what it was for at the start. 

I really do hope you make more puzzle games like these since this one was really enjoyable but I found it a little short for this type of game, 

Thank you for creating this wonderful game! I will be expecting more great games from you!

Thanks you for your kind comments, I'm glad you liked it. I work on a follow up to the game, and even if it's taking more time that I wanted to, I hope it will be as good.

Hey man, I remember playing a game that was very similar to this in a recent LudumDare jam. Is this an expanded version of a submission to, if I remember correctly, LD37?


Yes it is ! It's based on the same ideas than https://nusan.itch.io/non-eucl... but with complete new puzzles and spaces to explore.

The original Ludum Dare submission is here : http://ludumdare.com/compo/lud...

A end to a puzzling adventure!

Wow! Really awesome game concept here. Played through the whole game and enjoyed it very much.

Fantastic I really LIKE this game, I want to play more games like this

Super glad i have just finished this game! after 4 whole episodes! the hard work paid off! haha, very cool game, was super happy to play this, good job on creating this!


I had to create an account to say how good this game is. It's incredible! I love the design, audio, puzzles. Even that getting to the puzzle room is puzzle itself. Great work!


  • When you have controller plugged it you can not controll the game with keyboard/mouse. If you are lucky and start the game you just spin and walk left. I have had installed VJoy and that kept breaking the game until I uninstalled it.
  • In gravity bridge I found that randomly when you pick up the first box the second one disappears.

What would I change:

  • The ending. It's as mindblowing as the rest of the game, but squid with a human head? It looks kinda stupid for my opinion.

I found the secret! And I finished the game! It's excellent! :D

This game is absolutely wonderful. I really loved playing this game! I really hope you make more! Thank you for the game! I would really recommend this game, and I would also encourage other to pay a little as I have a couple bucks. It is a "name your own price" game, so this creator can create more like this, please don't be afraid, it's not like they are asking a whole bunch from you. Have a great day!


Please don't be afraid to like, subscribe, or watch more on my channel.

a piece of art ^_^ hope you like my video :)

Fantastic Puzzle game , The best i have played since portal !!

Now where are you ya damn laser?!

One hell of a genius trippy puzzle game! Awesome it's based on Escher's paintings. Mind blowing. Can't wait to upload the second part of my let's play!

Support this developer! They need to make more games like these!

Hope you like my let's play video, please help me grow and NUKE THAT SUBSCRIBE BUTTON HARDDdd!!

Thanks so much brovvv!

I really enjoyed the game. Very well made and well designed.

Here my playthrough:

I love M.C. Escher. Since I was a little boy I wanted to walk into his labyrinths. And there come the first level ; Wow. The dream come true. I was amazed.
But after 30 minutes on the game, I had a few things to reproach. I was not surrounded my the Escher Magic anymore.

The unique gameplay is only shown on Escher's level
Indeed after the first level the player face puzzles that are almost exactly the same as Portal ones, but with the non-euclidian gameplay. A cube, a button that open a door, doors that can "warp" you to an other side. A player that has played Portal already knows all the patterns about the great majority of the puzzles.
I think you should have drown your levels as simple drawings first, just trying to take up Escher's style, and not working on level design first.

The second thing that bothered me is a problem about level design. This game deals with labyrinths, and usually the direction the player must take is very unclear. Thus he attempts a way, but finish blocked and must restart the level from the beginning. This is not a cool game design, a player shall not be blamed for his curiosity and exploration.
Let's take the example of Portal, because it's the closest game. The levels are build so that you never have to restart a level, you can always "restart by yourself", going back to a point of the puzzle and re-create a cube if you have lost yours.

A last little thing, the font is not going very well with the voice. When I read it I feel the unfinished game. Maybe a font more holy, massive would be more appropriate.

Finally other than those things, great job. It will probably be one of my favourite games when all those troubles will be set.

Thank you for your remarks. Some of them I acknowledge and I want to address them in future releases or sequels. It's true that the latter parts of the game are more about solving puzzles and a lot less about interesting landscapes. Putting "companion" cubes on push plates may remind Portal a bit too much. I wanted the player to know immediately what he must do. But puzzles themselves are not at all the same than Portal (mechanics, solutions, ...). I hope that each of the 4 main puzzles can produce an epiphany for the player.

I do agree that exploring outside the main path is not very possible, and that you can get stuck in several puzzle, and being forced to reset. I didn't find simple solutions to avoid the player getting stuck, or loosing himself, or avoiding solving the puzzles. In the sequels, I will try to add more exploration level like the first room. I will also try to design puzzles with no fail state.

This game is realy cool, the graphic style is mysterious and the game is great. I need the second part !

Seems to be a great game ;) But I can't play. When I start it, the camera look up and never stop to rotate around y-axis (and I just see the ceiling turn).

Got an idea about that problem ?

Hi, this is probably an issue with a controller plugged on your computer. You can try unplugging gamepads or anything that could act like one. One person had an issue with a old 3D mouse driver that was installed, and uninstalling it made it work. You can also try to change the input mapping in the window that appear before the game really launch.

Let me know if any of this worked, sorry for the inconvenience and I hope you will be able to play.

Being a squid is fun! Enjoy!

I got brain****ed while playing this game. It was the best brain**** I have ever had. Love it.

This game was so AMAZING!!

I'm looking forward to play the next chapter of this history ;)

Thank you so much for developping this game ! It's my favorite

oh my god this game is so so so fun!!!! It's not too challenging, but still really really great game, 100%, 5/5 plain ol' good.

I just finished this game and it was AMAZING. I really hope that a sequel is developed in the future bc I would love to play it. :)

Sorry for a newbie's question, but how on earth can you turn around? I have keyboard and keypad only and with the keys I can move or jump only, not turn.

The game is mainly playable using the mouse to turn the camera. You can also use a gamepad (the left stick). Sorry for the inconvenience. If you have a special reason for not being able to play with mouse or gamepad, let me know and I may make you a special version with full keyboard mapping.

It works! Somehow I managed to not get the touchpad to work but now it's all good. Thank you.

Nice ! I'm glad you made it work !

This was extremely awesome. I love the physics and I can't wait for the continuation of the story. I even have a suggestion if that's alright. You could use the redirection of lasers to activate doors instead of just buttons and cubes. :-)

Thank you for your kind words. I also think that redirecting lasers through portals could be a great idea !

Overall I found this quite brilliant. I'd love to see a sequel or full length game at some point.

Last episode which covers the final puzzles!

Beat the game in about an hour of exploration and trying to get out of bounds to outsmart areas. Great time playing and looking forward to more!

Can't rave about this game enough. Really beautifully done with the puzzles and perspective. I added it to my latest countdown at #1 (not a rank, just where it falls on the list)!

Thank you, I'm glad you liked the game ! Great video btw.

Thanks! Good luck with all your projects!

Taking a look at The Run and Meeting puzzles!

round of applause, this was so amazing, would definitely buy whatever comes next

(Edited 1 time)

When running it on linux, the beam from the laser is not visible from the screen shot. Everything else works.

PS: Amazing Game!

Thank you ! There is some small bugs I need to fix on Linux, yes. What are you meaning by "from the screen shot" ?

The pictures on the game page.

Ok, I will take a look, thank you for the info!

It was the same for me.

htc vive maybe?


People are already kind of dizzy after playing for a while, so .... But I would be curious to see how it feels, being in that place in VR.
