You need to rescue the princess, and the only way to do it is to get through the castle of booby traps and dangerous lava floors! In this game you only need your left and right arrow keys to move left and right and your up arrow to jump. Sounds pretty simple right? Wrong. Every time you jump, the spikes or platforms or whatever you need to cross the room changes. Maybe it’s a box that you need to jump on to get out of the chasm, or the spikes on the platform you are ready to jump on.
