There are some really nice aspects about this game: especially the fact that less jumps gives you a higher score. That mechanic alone could make for a very interesting full title if you'd continue working on this! My score for level one was 9, and for level two was 18. I like the art too, you're clearly pretty talented :) Good job on making this in 48 hours dude!
Some feedback:
- I like the floaty movement, although you seem to get stuck if you cuddle up to walls.
- The jumping seems a bit fast and allovertheplace at the moment, maybe try smoothing it out a bit, or making it less fast!
- I would change the color of the spikes to something more outstanding and dramatic, because I sometimes confused them for normal ground, because of the same color usage.
- If you continue working on this, maybe elaborate on the color palette and background so the levels become more varied and recognizable!
