i will only suggest in two player mode "drop " "space key" to be palyer two and player 1 ,who control arrows to have ctrl or something near him
as hands confused this way
A little suggestion, the music files are wav format, perhaps you must think in make versions for other systems as MorphOS, AmigaOS4, AROS,and in these systems the wav format change to ogg via plugin, and make the executables more littlest.
