Pretty nice game,
I liked sound effects, and this whole thing reminded me of Doom.
The only thing is that I don't think I've could catch up after some of the eagles,
The concept is good, the visuals aren't bad.
There was a lack of writing, except that eagle spirits and hell and stuff.
Animations are clean through. Good job and keep it up!
PS: would add some more birds than just only eagles, but that's my opinion.
