Hi there, im unfamiliar with the fandom, care to give a rundown yap? :3
YAYY YAYYY YIPIEEE YAYY!!
Rhythm Heaven is a Nintendo game series which basically consists of different minigames where you press buttons to a rhythm :]
There are also a lot of very fun characters (wich you may or may not have seen me draw)
Also while the game is mainly rhythm-based, you can still unlock some fun lore bits through the game! (there's also the Rhythm Heaven Megamix lore but we do NOT talk about that)
There's also this fun thing called Heaven Studio, wich is a fanmade Rhythm Heaven custom level editor! There are a TON of custom levels made in that engine because it's really easy to understand it :3
Oh and also Rhythm Heaven Silver it's a fanmade translation from the original 'Rhythm Tengoku' (first Rhythm Heaven game) that never got released outside of Japan lol
I may have yapped a bit more than I anticipated uhhhhhh sorry about that
