Shroombon Action

Shroombon Action is a parody game both to Super Shroomio and Syobon Action. It's a short game with 4 levels and a final event.

Lore? Basically there's a lot of copies of Syobon Action, from Mobile bootlegs to literal copy and paste with changing the title to "Cat Mario", and this seems to be another bad copy of Syobon Action, until you notice you are playing as the final enemy of the game.

Also there's a cameo mentioned in the end of the game, but it's sprite gets corrupted every time, so just walk back after the cutscene in 1-1 to see who it was.
