Use the arrow keys to move your Green Block. Press the space key to pick things up, such as crates. If you step on the big red guy, you toggle horror mode.
There are different creatures, and they all want to come after you (for some dumb reason). Only 1 of them can go to different rooms. You must defeat them! P.S., I am sorry that I left the "start" variable in there :( I don't even know what it does!
