Bat Outta Hell (gruebite, jestbubbles)

Escape through 9 levels of hell using only echolocation.

Goal

Reach the end of the 9th level without dying. You die when you run out of energy. Use the echo's color to determine what something is:

• Green - exit to next level
• Blue - hellbug to restore energy, some will try to run away
• Purple - the rare gem, bonus score, only one in all of hell and its location is random
• White - outer cave wall (the cave is a rectangle), bumping will lose energy
• Yellow - pillar of fire, bumping will lose more energy
• Red - hellhawk, bumping will lose a lot of energy
