I deleted Spin Jumps Will Work, Boos' P-Switch Secrets, and Hotfooted in order to make room for new levels. I chose those because I have now altered them to add checkpoints; I'll re-upload them once I unlock more space. In the meantime:

11. Down to My Actual Cat Whiskers (SMB) - My first Costume level, starring Catsuit Peach (ha, just read that and realized the confusion that word could cause). Definitely meant to be a challenge. Multiple shortcuts throughout, but you'll need the Catsuit at all times. If not you're taking some trips underground, including a boss fight I was pleased to find a way to force you not to skip. 4586-0000-010C-4727

12. The Toad's Refrain (SMB3) - A castle-to-castle airship-hopping level, with no shortcuts, a mini-boss that might require you to think, depending on your power-ups, and a classic Bowser fight at the end. Tried to make this an "easy" level. But you know how that usually goes... 66E0-0000-0108-FB81

13. Throw Up to Grow Up and Go Up (SMW) - This level will make you throw up. A lot. ...I kinda don't want to say much else about it, because it's meant to be one you kind of "discover" as you go. Three ways to win, including a secret one that skips half the level. 87AF-0000-0108-FF30
