A fun shell hack with deliberate oldschool-vanilla-kaizo aesthetic sensibilities. I'd say this is fairly intermediate as far as shell hacks go. The setups are clear and helpful, but some of the tricks might be tough for newer shell players. It's funny to think that if you go back enough years, stuff like this would seem utterly outrageous for people to play. Nothing mean here, just a lota' shells.
Watch out for the mid-air shell jump and the mid-air key jumps if you want to find all the secrets and silly message boxes!
