Thanks Joshua for trying it out...not my best game at all but I appreciated your feedback and I agree with you!
The game should start slower and the tutorial should be different (help to understand what shape has to match with and have some buttons to go on in the tutorial...as it is now it's a simple unity animation lol).
But it is the first mobile game I made douring a game jam so...
Thanks also for the english grammar corrections too...as you can see I've to improve a lot my english skills :D
