Evil Stone

Evil Stone is a vertically scrolling beat’em up / platform game, released by Spacy Industrial in 1990.
Evil Stone is an odd game. It’s a beat em up, but rather than taking place on a traditional scrolling path, it takes place on grids of floating rocks. Furthermore, it’s a beat em up in which the player has no kind of health counter, and can theoretically take an endless number of hits without dying.
