Very well polished and fun, I especially love the environment, fits perfectly well with the story.
Btw is there any extra ammo in the level?

Currently in the levels themselves, you run out of ammo if you've already looted everything (a possibly large oversight after the addition of hard and impossible, but that should be expected given the untested button hiding them). In boss fights after the first however, regular drops of ammo are delivered to the player in the form of portable crates. Hopefully this answers your question!
