Here are all the grammatical errors I found. No comment on the quality of the storygame itself.
Steal the staff -> point it at a tree.
“"Nice." You say and chuckle a little bit, until the wizard, who apparently was still chasing you, finally catches up to you. "You, give me back my staff." He says, panting and out of breath.”
Needs to be a paragraph break between two instances of dialogue.
Steal the staff -> point it at a tree -> na na na boo boo.
Same issue with paragraph breaks between dialogue.
Steal the staff -> point it at a tree -> give it back -> break in -> question four.
“What is the power house of a living cell?”
Power house should be powerhouse, I think.
Steal the staff -> point it at a tree -> challenge him to a duel.
Paragraph breaks between dialogue.
Steal the staff -> point it at a tree -> challenge him to a duel -> hit him with the electric shuffle -> yes.
“You grab the cookie that falls from the sky, eating it and immediently dying from the seven hundred milligrams of straight uranium-235 hits your body and fries you inside and out. “
I don’t know if that word is intended to be immediately or imminently, but it’s spelled wrong. There should also be a ‘that’ between uranium-235 and hits.
