Here's a fun one. This also works great for getting medals on Newgrounds. At any point in the game, right click and select play. Also try fast forward and reverse.
Great game, but the keys often stick, walking me right into enemies.
Also, the fact that you can't finish the level during an alarm can lead to problems, such as an enemy seeing you right before you get to the exit. Surprise. You're screwed.
