Very interesting game. I wasn't sure if there was a way to look around the map, since my camera was stuck looking forward the whole time. I also don't really know what spacebar does, other than taking a peek at the next level. Movement felt a little slow, so for the first two levels, it was hard to get the right timing down to get past the enemies. I only made it to the fourth level before running into a cat.
The music certainly gave me shivers though. I also liked the spinning title and game over screens. The function tied to the spacebar seemed like a cool mechanic. If you were to improve on this game, it's worth looking at some ways to integrate that into the gameplay, I feel.
