User Summary
Foul Play is a set in a Victorian looking theater. It's drawn like a cartoon and is about humor as much as it is about action.
The protagonist is Baron Dashforth, a retired daemon hunter who stars in a show about his life. In this sidescrolling game, you have to defeat the villains (/actors) coming at you in all the different acts of the play. However, you're not supposed to just beat them up, you must try to do so in the most theatrically ways to amuse the public. They take up the lower part of the screen and your action will impact their behavior.
It's possible to play this as a two player co-op game, by calling in sidekick Scampwick.
