Thanks to Relfirm for the original project The Challenge. Arrow keys to move... R to use the checkpoint to go back. In some levels, you can cheese it.
12/16/2020: Added lots.. and added some easer eggs. Thanks to Relfirm for the BROKEN original project The Challenge. Credit to all for all. I added some cheese and some spike shedders... Just kidding. I added an invisibly frame mechanic that can be used to cheese. All 11 is possible by cheese+Check Points. May 12 2023: I believe the OG project was broken by a Scratch Update, but I do not know. I guess that an update broke some projects.
