it is a cute game and relaxing to play,
I do think that the UI for you booster of you jetpack and sprinting, is kinda distracting, so in the middle of the screen especially when it gets bigger. I also would like to have a shadow underneath the player, so when you jetpack around you can kinda see where you are in space, it would make it easier (I can guess this is part of the challenge, but after a couple of times "dying" because I just mist the platform, was kinda getting annoying.
but overall a pretty good game, I do like the art and sounds as well!
