Interesting game, I feel like it could turn into someone really cool. The movement felt a little forced for me, but I did like how you could upgrade that (oddly it didn't feel like I kept my upgrade when I went to another planet)
I would try and work on tiles for the desert level too as they tend to blur as you run, maybe make the tiles larger and spread the pattern out a little bit or just less intricate patterns maybe.
Great start just needs more polish and a gun please, I really wanted to shoot something lol.
