Punch-land

Punchland is a free platformer action game released and playable on actual gameboy hardware! 4 worlds with 2 levels and a boss fight each, 15-30 minute playtime!

It's got a super gameboy border, intended for GBC but playable on DMG, all original music, sprites, art, etc. 

I worked on this for about a month, it's a retake on my previous game Punchworld. This is much more fleshed out, of course.

It's also open source! https://github.com/monarchwisteria/Punch-Land/
