Find  The  Green  Square. 

By finding more, you'll unlock the variants and other challenges. 

The variants extend possibilities to shape your own rules thereby allow you to find your feel good way to play.

Essentially, the game aims to provide a relaxing / challenging experience depending on how you choose to modify and play it.

Furthermore, experimental scenes are regularly created to test different features. These scenes are not intended to provide good gameplay, but to test, experiment, learn and share what could (or not) one day be fully part of the game.



need feedback to know if the game provide some fun (or some kind of feel good) and if it worth developing it. 

If so, I have a lot of ideas for new challenges, variants and even more fonctionnalities.

Today, only the first single player challenge is some what polished, the others and  the chronicle are early exemples of what can be done with this concept.   

However, if this project does not lead to a real game, I intend to make it my learning and experimentation platform. I feel it could help me to learn new Unity tech. (machine learning, shader graph, ECS - c # job... so much to learn!)

The developpement is currently suspended.

I think the online version of the game is broken. Once it gets to level 6 (right after the level where the green is the last one), the game screen turns green and doesn't do anything else.

Oops... it is corrected.
Thank you very much for the reporting.

nice game but i think in "turn all green test 1", cubes should lose velocity

Yes good idea, I think I'll add "lose velocity" customizable variante at some point (most of the play modes have to be refined)
