It was really short and seems to hang when reaching the end of the level or when getting caught. But the audio was pretty good.
A couple of comments:
1. It's not a convention in any way... but I was expecting that if the character is moving upwards in the screen, it would be going uphill... Took me some time to realize that it was actually going down. I would suggest adding a few more elements to strenghen the impression that the character is moving downhill.
2. There seemed to be some gaps between trees so one could actually slide between them. Was that intentional?
