The Creature's Game

You've been asked to playtest a new game, something, you find out, that has been playtested by several others.  This isn't your ordinary game, though.  Something is a bit...strange.  What happened to the other playtesters?  What exactly is going on with this game?

The Creature's Game has intended glitches.  If you run into a glitch, though, where you can't get to the next page/area of the game, let me know.  Also, even though this looks like a game for kids, they may get spooked by it.  There's also 3 endings and a secret area that you can get to by hitting the D button or right arrow key, when you're in one of the hide and seek sections.
