The music and artstyle is very nice. Unfortunately, the biggest problem I had, is that the collision was very off. I was floating above objects and powerups can be stood on but only collected when you walk into them from the side. If the collision was fixed, this would be a fun, fast-paced platformer.
Overall, I enjoyed it. Collecting powerups to go really fast and using the jetpack at the same time was a fun mechanic.
