The adf should have been bootable but I can forgive you for that. I really liked the player sprite, it had a lot of charm and reminded me of Basil Brush. (If you don't know look him up.) Games don't need to have amazing pixel art and I dig your graphics. However the gameplay is pretty basic to say the least. Curiously every time the game played a sound sample my floppy drive would spin up which was kinda weird. The game is written in ASM though, which is more than I can do, and you have the source on github so I have to give you some extra points for that.
