Simple and fun to play, the movements are very fluid, for example, jumping over the clouds or climbing the stairs is quite fun: I will suggest to bring out this feature (make it more noticeable) for example, adding more platforms in the space, each one more difficult to reach than the previous.
I think the game is in a perfect state to be expanded with new features; moving platforms, new levels etc. Even more: just reusing the teleport orb that brings you into space can contribute a lot to give the game a "puzzle"-feel (take a look at Orbitel in this game jam)
Overall the game is ok, I wish it last longer!
