You just had to put a bunch of blades above the door at the end, didn't you. I was so excited the first time I saw that door, and yep... overjumped it. Dead.
Really fun concept. I'll definitely be coming back for more. Loved the way you implemented the mechanic of being able to jump, but at the cost of health (used a similar mechanic in my submission). You definitely *feel* the decision in your game, which makes for some compelling gameplay.
One bit of feedback... It felt at times that the amount the springs launched me was random, and other times it felt my next jump would be increased from my previous jump's height
