Great balance among difficulty and reward. Playing this game implies failing a lot, but as much as you fail, you learn and progress. I liked the bold use of the skate board as a base mechanic, and how it relates to avoiding enemies. Ninja stars feel like a skip-token for such mechanic, which is a great asset regarding the one-hit policy and the overall difficulty. There happened a little bug to me (for the record so you can review it): if you go upstairs without getting the device, the map will not change once you go down to get it and get up again, not until you die and repeat the level.
