yeah i guess its acceptable, Maybe tunning a bit for the gamejam theme... as for submission, usually source would be prefered... so that linux people can try to compile too, but if its not possible, then at least make sure there's windows 32bit binaries that are more compatible.

and as general rule if the game have a fixed resolution try to not make it bigger than 720p (or if 4:3 not bigger than 1024x768)
