Fun game! I really enjoyed running around spinning my gun waiting for the zombies to line up to get the perfect shot. I'd normally tie it into with saying something dumb with myself. The mechanics really lend itself well to feeling like an action hero and I think you can expand upon that in a lot of ways with some really cool trick shots and the like. The sound design was nice if not a little jarring from the UI, and the style of the animation was fun. The overall lighting of the game however was definitely a bit too dark imo. I spent my first run wandering around and didn't even find the staircase till my second just from being unable to see much of my surroundings. As well I ran into an occasion where I just ran out of ammo due to none spawning for me. Seems unlikely if you're getting big pierce chains on the zombies but definitely something that can happen. Maybe offering some sort of melee option if you have full style meter that can replenish a portion of your clip? Others have already mentioned the misaligned crosshair and it seems like you've already addressed it. Outside of that I think this could really benefit from having a stylized UI, something in the vein of a DMC. That would really tie the benefits of the style meter into a more immediate response to the player watching a combo build up with more and more style. I did enjoy the game and I think you've got the bones to make something really cool here.
