Oh man, this game's awesome.
I use a controller, so I can't speak for KBM controls, but this game is tight as shit, controls are great, some mechanics could be better than others, but the core gameplay of flying around, aerial acrobatics, dodging missiles and shooting shit is just spectacular.
This game is amazing. Rather short and not much replayability (although there may be some secrets or things that I missed/skipped when I played, I tried being thorough.)
The story, graphics, characters, plot/progression, are all amazing. I loved the art style from the beginning, and it only impressed me more as it went on. The ending is beautiful, in a way, although slightly disconnected from the rest of the story, it's more about the character, and less about us as the character I think, in that it's less about the journey we just went on and more about them living their own life, with their own goals and aspirations, we simply saw a part of it, and it was really nice.
There's a lot about the main character and world that we don't know about, so you might feel a little lost, but it handles it in a way that makes it seem natural when they're talking about things like forest god and stuff, as if it's just a part of their world.
Very enjoyable. 11/10
I love first person action games that may or may not include guns.
The mechanics work nicely, which may be the replayability bit.
