I'm a sucker for first-person shooters, and I'd be impressed just to see a functional one, but this is more than just functional. Even though the weapons are basically jokes, it feels surprisingly good. Movement is fluid and the tilt effect  

I'm not sure if I really like the visual style, but it certainly is unique. It's an eclectic mix, with picture of a hand, a bit of pixel art, bold environments and dramatic shader effects, but it feels retro overall.

That being said, I don't think the super dark environments where you can't see three feet in front of you without using your weapons as a makeshift flashlight were a good choice. They just made my eyes hurt, and were frustrating to play. The platforming section in the dark in Chapter 3 kinda broke me.

The minimal sound design is another thing where it's distinctive, but I don't know if I'm really into it. I think I'd personally prefer music and more sound effects for doors, enemy alert, etc.

Of all things, it almost feels like a weird DOOM WAD, and I'm almost surprised it isn't given how much it nails the 90s style.
