Flicker, a very simplest of games. You have a ball, it moves with the arrow keys. This ball has been granted the magic power to ward off the shadow by clicking space (Space lets you see things in other words...). This ball, has one 'Achilles Heel' so-to-speak. That being, that if it strays from the line, it will, undoubtedly die. You mustn't use up your power to quickly, it does replenish when you start a new level, but it drains quickly, so only click space when its needed.
Currently just 20 levels. Found it quite a fun little game myself, wasn't to much of a challenge to make.
