You wouldn’t think a rhythm game can really have any ability to be speedrun, but people will make speedruns out of everything.
The best example of this is Rhythm Heaven, with the speedrunning being popularized by Jaiden Animations, and the differences are mostly about the speed of using the menu.
Another game like this is osu!, which has categories like an amount of FCs or an amount of pp. This has the added challenge of finding the best maps for the fastest time. The times can get surprisingly quick, like this 7500 pp run in less than 10 minutes.
I think it’s possible to speedrun Patapon since it requires a lot of skill to keep it in fever the whole time and also not fail the miracle drums.
True, looking at it in speedrun.com the series has some runs, with some new ones in the last month. I wonder how that’ll change when the similar game Ratatan comes out.
