Loved the idea ! The audio is good, the art style polished. I enjoyed the gameplay, even if I didn't went beyond Lvl 4 : found it a little too long and repetitive, even with a lot of good idea for variations. There was no real reward in sight keeping me trying, maybe displaying the number of levels could help (so players have an actual goal in sight to reach).
Overall, it's already a really good game !
Ps: With no web build, very few people will rate this game (they're usually too lazy for dowloading an exe/apk), you should try to make one next time.
