I love platformers, and this is a great start. Take it and run! I agree with the jump physics, they are a little weird, but my biggest issue was the lack of solid walls. Run into a wall, and it jumps you all the way up to the top of it. Made things pretty funny actually. Then you could also use a death spot at the bottom of your map, cause I fell and had to reload to finish it. Overall, great first attempt, go to it.
