This is wonderful, one of my favorites in the jam! The game loop is great and it gets you hooked to wanna play one more after running out of battery. The visuals are great, the sounds really add to the mood. Maybe a high score table would be a good addition. Awesome game, well done!
ps: I would like to second heckert about the source code: rar archive in the github? :D If you could do another commit with the extracted files that would be nice :)
