It might have a few bugs, and FYI it's not finished yet (it's one of my biggest projects. As you might notice though, I am a intermediate scratcher. I only used this for around 1-2 months.). And as for how to play, the only thing I left out in the game is to shoot the fireball, press space.
I used a lot of scripts from: 1. DOT on scratch (a cool platformer) 2. Scratch Wiki (very helpful) Those are the two that helped me a LOT. Thanks to those two web sources!
