You, Glumbo, find yourself trapped in a chamber that is rapidly flooding with dastardly creatures known as "squares" and "triangles". Truly evil...
Collect coins as fast as you can and unlock the exit before the onslaught becomes too much to handle.
I will warn you: this is a difficult game. You are going to have to be smart with your movement if you want to beat it (No, running in a straight line will not work).
Especially in Abandone Hope mode, you will need to be constantly aware of your surroundings and listening for sound cues to win. Don't say I didn't warn you, because I did.
