Supraland: Crash is the first DLC and is on its own right a pretty standalone experience.

In Supraland, you get the stack of coins, and then you discover a curated puzzle based off the exploit/difficult movement you just did! There are puzzles hidden in secrets that are itself a secret in a puzzle that you completed a while ago, but now that you know you can burn cardboard, there might be a new secret puzzle to go find while you're exploring with your new movement options. If you get a dopamine kick out of breaking out of Mario Odyssey's intended boundaries so you can stack up a bunch of coins, or leave a Luigi balloon there to confuse and intimidate others, Supraland is your game. How I would bill the game, is that it is the secret-seekers Nirvana. The original game was made largely by one person and billed itself as a majority exploration/puzzle game, with a small amount of combat that wasn't great.

Every main upgrade you get in the game is a slap to the face in how you move in the world, everything changes and has you look at navigation/optional puzzles from an entirely new perspective. Literally, you're a tiny Meeple from Team Red that has to go solve a bunch of problems caused by Team Blue that are fundamentally breaking things in the sandbox the game takes place in. Supraland is a first-person indie Metroidvania where the majority of the game is set up around puzzles using wildly varying movement mechanics in an open-world sandbox.
