Thanks for playing Tomodev. I remember you commenting about picking up Goblins in the last Demo Day - you don't pick them up.
You probably couldn't Dash, because you ran out of Mana.
You can disable the green slime pools which slow you down, and you are unable to jump from in Sealing Chamber. You can also give yourself more time, add more abilities, and more in there.
