This was fun, I like the implementation of the anti gravity mechanic, it made the levels have a nice challenge once you were upside down. I played thru the whole thing and didn't have too much trouble with any of the levels. I think I'd make the barbed wire hitbox a bit smaller, some of the jumps with a spring surrounded by barbed wire on both sides were a little frustrating to pull off. Great job on this I had a fun time playing thru it!
