Sounds like you spent ten minutes on this.

It feels a little too... simple. It's definitely too short, as well. True, it's a loop, but too short and simple of one to even be used in a game. Try having a real melody instead of that five-note pattern that plays throughout the song. The percussion is also repetitive, as well - maybe not to the same degree as the five-note pattern, but still very repetitive. Try making this longer, and then changing the percussion at a later point in the song. Just trying to help - I hope I did. ;)
