Well, it is fundamentally a puzzle game, rather than a platformer. (Like Klonoa, back in the day.)
Its primary hook is time manipulation. You start out with the ability to reverse time by holding down x, and the game introduces mechanics that play with this: certain enemies or bits of the environment won't be affected by your time manipulation, for example.
Say you've got a key that's unaffected by time manipulation that's in a little alcove that you can't fit into, but a goomba can; and just past where the key is sitting, there's a spiky death pit. So, what happens in the course of normal time is that a goomba walks into that alcove, picks up the key, then walks to his death in the spiky pit, taking the key with him. To beat this puzzle you'd let the goomba walk into the alcove and pick up the key, then reverse time so that he'd walk back out of the alcove and bring the key with him; then you kill him and take the key.
That kind of puzzle might appear in the first accessible world. Later the game introduces different mechanics: like, in I think world 5, when you walk right time moves forward, but then if you move left time moves backward. Imagine that there's a locked door to your left and a key to your right: you move to the right to pick up the key, then to the left to use it to unlock door; but as you move left, time goes backwards and the key floats back to where it was.
Later still the game allows you to record a shadow of yourself: say you walk ten steps right then jump, then reverse time so you go back to where you start; when you stop reversing time, a clone of yourself will walk ten steps right and then jump, while you can go off and do something else.
The game plays with these mechanics to produce really inspired puzzles, and inspires the same kind of fuck-I'm-clever feelings that Portal did, when you figure them out.
Plus, it's beautiful! Its aesthetics remind me a bit of old European Amiga games, except with the detail ratcheted way up. It's nice to see a sorta-cutesy 2D game that isn't typically Japanese-looking.
Anyway, I don't think I'm capable of doing it justice. You really need to play it.
