It worked for both the emulators I have on Linux. Pretty basic, but cool. The jumping was a little odd, because it seemed like you had the flies set up to collect 3 off of a jump, but it wouldn't quite line up for me.
Yeah, it was my first homebrew and first time writing in any assembly language so the game did turn out pretty basic. Insects were actually supposed to be randomly spaced, but pseudo-random numbers on the Game Boy was tricky for me. Thanks for the comment and feedback!
