Very nice concept and so so polished game at all level, you can directly ship it !
First minute: mhhh strange, if I turn 4 time each tile, I will win all the time, very strange, not fun...
From the second minute: Holy shit it's pattern based like a rhythm game and the feeling is so satisfying !!!
Maybe one little modification I will be happy to see is a tuto/warm-up level, like level zero, where you just have to right click one time for a line of 4 or 5 tile, to show the feeling and the goal of the game. The first level is too complex to see that for a first time experience.
Also happy to see other french people using Godot :]
