Great character animations and nice music! The cover art looks good, too. Gameplay works well most of the time.
Criticisms/Suggestions:
Sometimes the character refused to jump.
The music didn't loop. Once the song was over, it never played again, even on restart.
There's not much gameplay for an "infinite" runner - there are a few holes and obstacles that repeat constantly, there's nothing new to see after a minute or two. Could have more obstacles, and (based on the lore) having the ground actually crumble behind the player (and catch up if he gets stuck on a wall).
