Is the FOV Mod I can find in the Fluffy mod manager the correct one that's allowed? And also are there limitations to what the FOV can be?

No, the official mod is pinned in the #tools-development channel of the discord. It's made by one of our community members, Squirrelies, and does not require mod manager to install and use. There are no limitations that I'm aware of, but speaking for myself I'm not a huge fan of watching runs with the FOV turned up over 105ish--makes me a bit motion sick.

Is there a video somewhere to show how it works I'm really dumb when it comes to this stuff and I can't get the FOV mod running

I don't have a video to put on here to prove that i beat the game in 1:56:00 could someone help me out?

@Eva0123 we require video proof of every run unfortunately.
