I really liked this game. It's very well done and the movement overall feels good (although maybe just a little bit too 'floaty').

The level design is ok for the most part, but the section in the third level where you have to ride a rocket through a tunnel is terrible. It's too hard and not in a good challenging way. Some of the obstacles give the player literally no time to react, so you have to memorize the obstacles positions, and even then controlling the rocket in that very narrow tunnel is a nightmare. Even after many attempts I could not get through it. If I were the level designer, I would make all the turns much less sharp and remove all obstacles that are in the midle of the turn - they are the most unfair ones because there's no way of seeing them even a fraction of a second before it's too late. And I'd also make the tunnel just a little bit wider, like 10% wider. I think those changes would make for a challenging but fair section.
