It's a game-game in a way reminiscent of A Hat in Time, following a strong theme but being undisguised gameplay first and foremost. It's got so many puzzles, powers and possibilities and just an unbelievable amount of stuff packed into it, it's a joy. This also makes it thematically ambiguous and uninspired, there are a lot of fourth-wall-jokes and references that aren't surprising or clever. But still, good fun for a long time and there's more coming.
