Thank you for the nice comment. I would describe the scratch dash/tornado as a sprint but if you mean a run button, it's the same button as the dash. Holding the button makes you run and pressing it makes you dash. I didn't make a tutorial because it's part of the fun to find out yourself. You don't need the charged furballs for this spirit container, there is a second method. You can stack small furballs on the left or right high ground. It's completely optional to discover the charge ability. I was even more surprised that tunegoro found out that you can defeat invincible enemies with it, didn't expect anyone to discover this already. Thanks for spreading the word :3
