Solid first game submission. I did notice though that whenever you double jump in the air while horizontally touching a wall you fail to jump. I do also wish that the colors were more apparent on each of the devices, especially since some are hard to discern at times. Also, the booting-up sound can be a bit jarring. Beyond that, I'd like to see more variety in the game if you continue to develop it. Very decent game all around, good stuff
