So basically I have recently been doing the Undertale Demo Speedrun blindfolded and I thought that could be a new category as it is interesting and hasn't been seen before in the Undertale Speedrunning Community. idk if anyone agrees but it would be nice to have somewhere to record my speedrun attempts.

I agree, it should have more categories

I think an that's a great idea, maybe you should find a way to reach out to one of the mods and make it a thing. I feel like if it was a category here I'd try to learn it.
