Nice game ! Despite having only one touch, you successfully made a game with some depth of gameplay ! :D A bit hard to understand the interaction with some walls (i was spamming at some point) I am just sad that it has only one level !
I received that feedback several times, and I'm thinking to add some friction with the wall so you have time to react rather than spamming. I may actually invest more time into the game and make 2-3 more levels.
