I partitioned my iMac and installed Windows do I can try it out. I’ll get back with a rating for ya.
EDIT - Wow! The low poly artwork is really polished looking. The fox running, turning, and jumping animations are clean. Camera movement is smooth. The music is nice and calming. The dialogue from the bird (introducing the gameplay) is paced well. The movement control feels nice and tight. I had a couple of rendering issues. It seems you've included some post fx and they're just not displaying correctly for me in parts of the level. If I get too high (up on a high grass platform) the sunlight pretty much white washes the entire screen. Other than that, I enjoyed running and jumping around as the fox. Rated - awesome jam entry!
