Some joker spilled butter all over the Underground! How inconvenient! But that won't stop you, will it...?
This is a challenge mod for Undertale Yellow which takes the slippery floor physics from the Jandroid battle in Steamworks and applies them to every single encounter (and more!). From Marlet to Zenith Martlet, from Ceroba to Geno Ceroba, from intro Flowey to final Flowey, this mod covers all the bases... in butter.
See if you can beat the whole game like this! Every encounter has been vetted to make sure that every route is beatable. It may not be easy, but who said that finding the five missing children would be a cake walk?
Bonus challenge: See if you can no-hit the game! Though don't spend too much time on that, I'm fairly sure it's not actually possible. But you're certainly welcome to try!
