2D Fighter Maker 2nd game. 1v1 2D fighter with an all-female cast. Has an extremely generous demo that has all the characters from the full game, the only difference is that the full game has a long story mode with cutscenes, so it’s more than a demo for me. Available for download on DLSite

1v1 2D fighter. Basically a doujin take of the classic Nintendo game “Joy Mech Fight” made for PICO-8. It’s really cool and has some cult status. Seems that a Steam release is also coming in the future. Also don’t forget to check “Robo Oh vs Uchu Mega Fight”

A kinda shitty 1v1 2D fighter heavily inspired in “Mortal Kombat” to the point that even the sound effects were stolen form that. It’s a very humble indie project so I’m fine with that. Atari Falcon port has music in the matches and a slightly higher color palette, but seems to be the same game
