Was ok.
It's a nice game, that's for sure. I like the presentation, great atmosphere thanks to the background music and also nice details in the environment - but those were also often the problem: It's okay that you must not collide with anything, but tiny details were placed a little bit too wrong here and there.
Loved the plot of the game, but like some people pointed out: It somehow wasn't that satisfying. The game frustrated me a lot (especially in the screen with the guy smoking behind the door - the way up was too narrow at the beginning), which I think is part of this creation. I wanted revenge on that bastard who shot me down to hell - but, when I reached and killed him I expected something else.
I played through this only once, so I instantly died by touching the credits which scroll up in the last screen. DAMN, there was the last key I got! And I didn't save, because I got used to 'retry' after losing all my feathers! That was a real letdown.
But let me tell you this: I'll try again soon, that's for sure!
