What is your suggestion, and why should it be implemented?

Title. Hide the keybinding/options for the character select screen until you've unlocked it.

Why? Well, afaik, you're not supposed to know that you can even swap characters until you complete weekend 1, especially with the cool intro the character select screen has and everything.

The only problem I see with this is if you can't actually change the keybinding and you don't know or might forget the keybinding to get in (It also doesn't say what the binding is when you're in the freeplay menu and have just unlocked it).

While I would implement this into my edit of the character select stuff I don't know how I'd avoid the above issue.
