Probably 'My Hero Mania'. Even though it was just in the stress test, it's the best 'My Hero' game I've ever played on Roblox. Oh, man... Especially the combos that you can do with engine quirk. I could do a 1-shot combo on Urakaka (which is the strongest boss in the game).

Well, here's the problem;
Bloxburg isn't a "mini-game", it's a game. It's not considered a mini-game because Roblox isn't a game. It's an app that has games.
There's also a game called "Epic Minigames". If Blocksburg or any other games on Roblox were labeled as a "mini-game", then "Epic Minigames" would be "Epic Minigames Inside a Minigame".
