I feel like maps that were made before 2010 are kinda meh... But then I remembered when I first started playing, I just searched for maps from anime and games I liked, and some of them were actually kind of rather bad quality older maps. x'D
I like maps that are fast and challenge my reflexes, but flow in ways/patterns my brain can actually process. Sometimes you just try those maps and you can't even... I can't read AR 10 yet.
Ah, I still need to try playing songs with mods... A lot of high scores have double time, but I can't stand the sound of sped-up songs. xD Hidden, I'd have to get used to. But it's probably the easiest mod to get into first... I think.
