THIS is how to Design a 3D Platformer!
3D Platformers tend to be frustrating to me, because it's often difficult to know where you're supposed to stand, and one little slip means a tedious waste of time getting back to where you were. Here, traversal is so smooth, and level design is good at making you feel like you know what you're doing. With the numerous grapple points, you'll rarely find a slog if you do manage to fall. Skating around on the ocean is really fun and satisfying, too. Since there isn't any real open-world exploration, a quick-travel system would've been appreciated, but backtracking is pretty minimal, so it's not so bad. I could've done without the few racing segments, but they only give you money, which is only used to purchase cosmetics, so they're skippable.
The world is absolutely beautiful, especially the water; the dark, shining colors beneath the waves and lovely skies and sunsets above come together to make an unforgettable aesthetic. Character models are fun; maybe not quite beautiful, but they have a neat cartoony aesthetic that helps to set the tone of the game. The writing, like the character artstyle, kinda screams young adult novel, but don't take that to mean that it's bad; the story is still earnest, and the characters are very likable. With all that in mind, the brass-heavy music seems a strange choice, but in the moments where it needs to be, it ramps up and becomes oddly compelling. The length is a bit shorter than it could have been, but very close to just right, and I'd much rather a game be too short than too long.
This comes highly recommended to 3D Platformer fans, and also to those who'd like to be 3D Platformer fans.
