Easily my favorite Doom WAD of all time. I played through the entire thing in about a week, and it was a blast all the way through. It's the perfect mix of whimsical silly mario style fantasy and Doom's hyper violence.

The weapons are full of personality. The platforming is stellar. The music is perfectly fitting. The boss fights are fun and exciting.

I can't get enough of this. I'm thinking of going through it a second time soon.
