Honestly, really impressive, I myself am always baffled by people who can make fully working games with no help of proper tools.
Everything seemed to work seamlesly as well, gwaphics, sounds and gameplay are all as perfect as they can be within the thematic (and technical, I assume) limitations, altought that means that, as an actual game, there's really not much to comment on here due to the simplicity, but I still think you did a great job at everything game design wise. (This is definitelly way better than any platformer I could see being released for an actual brick phone, that's for sure lol)
Anyway here's a gameplay vid if you wanna see it
