RuneCrusher is a transformation platformer game created in the Multimedia Fusion engine by Catastrophic.
It's a platforming game, where the goal is to get to the door while avoiding the traps.
Each trap has a different game over screen that involves transformation.
When a player is caught by a trap a small mini-game appears. If they manage to win they can continue to play, and are unable to be hit again for 4 seconds, if they fail they are transformed and must start over. The minigame gets harder each time (Becoming impossible at a certain point).
A really fun game, but difficult, too. Especially given there's no save system whatsoever. I still haven't gotten past the first room, only as far as the plants at the bottom of the screen. With no cheat codes, no saves, no debug mode, etc., this really makes it rather frustrating to try and get through the game.
