Pretty solid game, but you should seriously reconsider building for windows, I'm sure you can get in contact with the jam hosts and they'll let you.
Either way it's a nice little relaxing game, my only complaints are that you die too soon and that you should be aware that not all phones are suited for heavy-visual games. Try putting a setting to toggle textures and effects, or only load what's on screen.
Also, you have to drag the pad from the center to the direction you want to go in, this makes it a little clunky.
