Really enjoyed this - it was a reminder that a game idea doesn't need to be overly complicated to both be fun and challenging. It took me a good couple of tries to get through the second level (and I think I lucked my way through the third first time), but I got a better idea of the combination of manoeuvres I had to make each time. My only two critiques would be that the music was too loud and one of the batteries on the second level didn't respawn after I died (the one to the far right of the level). Other than that, nice little platformer!
