It's clear a lot of effort went into this- what you've achieved in just 10 days is very impressive! The amount of variety in terms of characters, items, weapons, enemies, etc. is insane. Also, I checked out the main page and saw all the effort you put into following the restrictions of your target hardware. It definitely paid off! Everything from the controls to the spritework to the music hits the retro feel perfectly and makes for a really fun game. The Zelda II reference was also not lost on me :) Nice work!
