Very fun. Nice chunky controls. My only concern is what I call the leap of faith problem.
For example, you jump over some obstacles and fall, but you can't see what is down there. You can land on a hazard you couldn't know was there, cannot avoid, and instantly lose.
This removes skill and replaces it with luck. Which is one way to go, but can get frustrating pretty quickly.
I'm not sure what the fix would be, maybe a quicktime event or something if you hit a hazard that was offscreen when you jumped. Or maybe bullet time in some form.
Also, are the levels procedurally generated? If so, well done and very cool.
Thanks!
