Super solid and pretty awesome. Love the art direction and look of the game. Some times it felt like the spawning of the planes was a little unfair, but it wasnt too punishing. It did take me a while to figure out that the helmets on the top right were my jumps. Maybe move that UI element towards the bottom of the screen would help cause I was mostly looking down there for the planes to jump on.
Great game, very fun! Would love to see it as a mobile game.
