Revenge of the sunfish is a freeware pc game by Jacob w. Buczynski which was released in April 2007.

The game was made using the games factory and most of the graphics were hand drawn using ms paint.

the game contains different styles of game play including platformer shoot em up, obscure puzzle elements and some horror elements.

Unlike most games, ROTSF can be beaten almost entirely by dying on most of the levels, this is because dying takes you to the next level anyway. This is considered by the author to be a feature.
