Here is the game, I’ve finished gameplay and pathfinding (and it’s very efficient) now I’m going to work on the leveling progression.

Actually the gridsize is 3*3 (the beginning), with 9 case patterns it’s work great (and it’s really hard), I’m going to do a gridsize that grow with your leveling.
I’ll add a timer to force the player to play (otherwhise it’s easy to find the good path before playing).

No arts actually, it’s only circles, I’ll probably made some arts and the game will upgrade visually, if I got the time for this.
Here is 2 screenshots.

It’s working on mobile obviously and with fingers it’s funny
