I know I've requested 1CC categories in other games, but this time I come prepared with a video to start the category, at least. This also has the benefit of containing a great glitch in Stage 2 that saves 30 seconds, so it can be used in Any% as well. The final time per Avidemux was a 22:22.

Can we make this a thing?

I would also strongly second this. To me, the increased number of enemies and more boss hp is very similar to an Easy run vs a Hard run in other speedruns like Turtles in Time (Snes) or Hyperstone Heist. That doesn't even take into account that it's all done on 1CC. I feel like this would make it worthy of its own category so that it can be more clearly compared to runs of the same difficulty (instead of just a filter).

Not (yet) a runner of this game, but I'd say it's a great idea. Did that with Ninja Gaiden (arcade): any% is the more accessible category, whereas 1cc% is considered "hardcore".
