Absolutely love the style. I can imagine it was a risky move to spend so much effort on an intro animation, but it is very much worth it. It really set the tone with that perfectly timed metal music kicking in.
The game feels very polished and cohesive. It takes a good minute to become somewhat comfortable with the controls, but luckily the objective is very straight-forward so this balances each other out nicely.
Shooting and reloading feels very satisfying, and the recoil moving you backwards is a clever downside to prevent the player from becoming too trigger happy.
It put a big smile on my face, awesome game and great submission to the jam!
