Hey Bamboy, Nice work!
Lovely presentation and spritework in-game and despite the lack of sound I had a good playthrough to around level 11 there which was pretty nice! The mouse controls marred the gameboy-ness of the game for me a bit but yeah, a nice entry overall.
Here's my Gameboy ROM Biotic Limit, good luck!
