What was that batprince duck doing at the very beginning? How did you do that?

To go against the masses here, I think that there are runs that require tedium that would still be worth while categories (or maybe that's just me being selfish, not sure). I would personally find it interesting to take on the task of MarinCa collecting categories or even something like 100% seahorse races.

Thoughts on MarinCa runs based on levels (shallows, depths, etc.)?

Hm what time do you think is the lowest this category can go?

Great run by the way! I can't wait to try and challenge you for it :P

Wondering if anyone else is feeling crazy enough for a full game speedrun (storymode complete), or even a 100% MarinCa speedrun (except for GYAO maybe, jesus)

The Golden Phase disc is the one you're most likely missing. You have to clear Danger Zone all the way first, and on the first floor reset, you have to only clear the tiles that have the darkened glass beneath, like you're making a target. That will cause the Golden Phase disc to spawn.

Here's a picture of what I'm saying: https://imgur.com/a/9dn0q2J
