I want to make a Taiko no Tatsujin-like game

I want to make a Taiko no Tatsujin-like game but I’m not sure where to start.

I’ve worked with rhythm game engines on roblox before, but those were open-source engines. I’d need to make an engine for the game from scratch.

If you don’t know what Taiko no Tatsujin is, i’d recommend looking it up to see what I’m talking about. It seems like it’d be a fairly simple concept to make but I don’t know where to start at ALL.

Any tips would be appreciated!
