I was just a tad confused even after reading the description, but it was a pretty cool idea of a game. The sfx made me jump the first time actually cause I had my speakers too loud and didn't realize there was sound haha.
A minor suggestion: Adding in music goes a long way, it just makes the project feel more full and complete as the player plays and takes very little time to add in.
Overall, this was a good start for a project, especially for one developed in only two days. Keep up the good work!
