Nice idea. Needs work.
Okay, the game was really nice and somehow addictive. You wanna know if there is an end or something (at least I do, so I'll play on and on and on...), I mean 'no return' doesn't mean you can't make it out, or does it?
But I agree with the other people, it gets kinda difficult after a few secs, but that's okay, it's challenging and not too lame, though it could be a biiiiit easier for us mortal people. :D
I can't say much about the music, I've disabled sound.
Next point: the medals. It's okay for me when I do not know how to actually get those medals. But at least I wanna know later what I've done to receive them, know what I mean? It's just strange for me that I got three or four of them when I jumped against a corner.
Well, another point, off the actual game, is that when I wanted to click anything in the menu after dying it wouldn't lead me there (Facebook, Twitter, teagames, leaderboard, more games, and oh, the box in the right corner in the achivements menu that says 'click here to....'). I don't know if it's just me? Maybe anyone else should try out to be led to one of those pages.
Okay, all in all your game was nice to play, no massive negative points in here but a lot of fun to keep me playing gor a long time.
So then, I gotta find a way out the cave, see you.
