The graphics and concept are impressive. I found the difficulty to be highly RNG-dependent. Any time I had to make a double-jump my chance of success lowered and since the layout of the obstacles vary from run to run, sometimes a level would be very easy other times very hard. I think I also misunderstood the controls. My intuition was that holding space would increase altitude but since it was jump-based, I automatically made the assumption that I had to make the jumps from the bottom position (incorrectly). That obviously makes the game very challenging. Overall I think it was really good. If the spacing between barriers were increased but the plane speed was also increased, I think it would be even more fun.
