Super Mario 64, but every floor is slippery

A silly hack where I made the floors in Super Mario 64 to act like sliders.

If you know how the game's geometry looks and how slide physics work, then this is the challenge for you. All 120 stars are possible and some of them require advanced knowledge, skill and determination. Also I've added the option to exit course at any time in case you're stuck on improbable floors you can't get out of. Enjoy!

[This was meant to be part of the Slide Hack Competition 2024, but I decided to dismiss my entry out of fear from being disqualified.]
