I love myself some biblically accurate angels xD
The story introduction in the beginning was actually kinda cool for how short it was, mostly due to the visual effects. I also liked the sound design and music mixed together with the visual aesthetic. Everything blends together nicely.
I did have a little bit of a problem with some of the generated parkours. The spiral staircases were actually really cool and with a bit of practice could be traversed pretty consistently. But the huge bars that would be in the players path were really hard to jump over from a distance without running into them first. I would have maybe liked a stage between walking and full out sprinting to be able to navigate these bars and also the platforms better. But then again it was also a nice part of the challenge that you really had to toggle shift a lot of times in quick succession to get the exact speed you wanted.
Overall a really nice game with a cool vibe. I definitely see a lot of potential if you'd choose to polish this game some more :)
