Amazing game! takes a bit of time to figure out a setup with the ore placements. But once you figure it out, the enjoyment of the game is more than satisfactory.

I like this a ton (pun intended).   And darn it, I want to pause that GIF image to observe the set up better!  lol

This is insane. I cannot believe you managed to do this on PICO-8. Literal insanity.

Hey, is there a chance for fullscreen steam release with achievements? And without those black borders...


Please add a tutorial.


A certain Yahtzee Croshaw has a lot of explaining to do.


Have you ever heard of Factorio dude? He doesn't have any explaining to do.


This is the monstrosity my sister made

This game was amazing! The design is pretty simple and the gameplay was great! I managed to make a pretty satisfying factory that took awhile but it was worth it.

What is that "boot-up" screen?

I have seen that and similar ones very often but I have no idea about what they are called or if I can find an example video that I can slow down and pause.

Thanks for any help! Great game!


Hello, that boot-up screen is coming from the Pico 8 fantasy console. It's a program to make small games at it's what I used to make DeFacto. You can find more games like that on the official website and even buy Pico 8 if you want to make games yourself.

The more you know.

really enjoyed playing! ended up building a really satisfying factory

Really fun!

Sadly the linux version doesnt work. I open the game click new game then click new world and it doesnt do anything...


Extremely good game! It reminds me of factorio and mindustry, but this is a more calm and casual experience! I'm only playing in the browser version but I have a few suggestions...
-You can't place things on top of deposits, which can be extremely limiting if you're making big conveyor systems. I would like to be able to place things on top of deposits, or have the ability to remove the deposits and replace it with ground.
-I would LOVE to have a save feature on the browser version. It sucks to know that your progress isn't going to get saved. It would also be easy to implement. Lots of browser games have save systems.
Overall; Great game! 8-9/10

Hi, thank you, I'm glad you like the game! I released this game two years ago so it's unlikely that I will work on it again. About the save system, it is available in the browser version as well! You can press enter and select "save", then if you close and open the game's page again you can select "load game" in the menu to reload you game. Be carefull as there is only one save available at a time and it is stored in your browser cache, so it will be deleted if you clear all your browser data. Have fun!

Thank you so much for your help! It's a shame that the you're not working on the game anymore, but I respect your decision. Hope that you'll keep making amazing games like this one!

Loved this!!

Stuck on the start menu.
I even reinstalled the game completely (uninstall then reinstall), no change. I only managed to start it once.

[new map] [new sandbox] buttons have the same effect as clicking [ESC], and the [new map], [load map] buttons in the pause menu don't do anything.

Sad because I like it.

System : Windows 10 pro 64bits | Linux 64bits

do you just click or cycle with the arrows and confirm with enter?

As far as I can remember, both of the inputs had the problem... I changed systems twice since then, haven't tested on my new system yet.


Fun, kinda like a easier factorio. Finished it in one single playthrough (it means it's cool and fun)

Thanks, I'm glad you liked the game!


NuSan, I love all of your games, but know that I'm craving for a sequel for Fragments of Euclid. It made me an addict! I may even try to do a game with simmilar mechanics by myself.

Thanks for your kind words. I'm working on a sequel for FoE but it's not nearly finished. I encourage you to start working on a similar game, it's fun to play with those mechanics and there is so much to explore. Here is another game you may like to try: also there is Antichamber and soon (I hope) Magnifold Garden.

I already started trying to code something similar, and I think I know how to make the teleportation thing but I have absolutely no idea of how you did the many reflections thing that you can see in "The Tower". That really blew my mind. I mean, when you look at a door, you see what's in front of the other door. I mean, again, in the tower, instead of seeing a wall, you see what's in front of the exit door in the next floor. You'r game did that in a great way, so much that it feels real.

Gosh I have so many ideas!

And thank you for those recomendations! I really love these kinds of visual games, where you need to see the world in a different way in order for you to finnish them. I also recomend you the game, which is really interesting and has a very cool dark ambience. And also try . All of his games are really strange optical illusion things.

You got me curious so I looked at asset from Unity Store and there is quite some:

There is free ones like

This one seems really great (but not free) and can play on scale (spoiler for FoE episode 2 ...), and there is a demo only

Even if you don't use Unity, it can be great for learning. I saw video of Memory of a Broken Dimension but did not know it was out, I need to try it!

One more IMPORTANT thing; can I get the OST of Fragments of Euclid anywhere? I can't find it anywhere on the internet and I really, REALLY love it

You can find the OST, as well as other tracks, on this page from Legulysse, the creator of the sound track.
I will also add the OST to the page of FoE today.




I'm terrible with this kind of game, but it doesn't change the fact it's really nice !

Wow good work

Fantastic work! Being a huge Factorio fan this made me smile and entertained :) Thanks!

Wow, awesome game, I love it!
