I didn't play the original Klonoa and the remake looked like an alright platformer but not a game I'd enjoy all that much.

Yes, I'm playing it now actually.  I never played the original Klonoa on PS1, so I never knew that it more or less invented the 2.5-D perspective.  It's a fantastic game; certainly one of the best 2-D platformers I've played.  It's lots of fun,  and it has great graphics.  The story is also absolutely ridiculous, but it's fine for such a cartoony, childish game.  My only complaint is that it's a little bit on the simple side in terms of gameplay.  I guess it didn't sell too well, because I haven't heard much about it since it came out.  Even so, I would definitely recommend it to anyone who likes platforming games.

I bought it two days ago, and finished it today. Very nice game. Kind of drags towards the end, but the platforming is solid, the game looks great, and the soundtrack is superb.

Yeah, the soundtrack is awesome.  I remember playing a PS1 demo back in the day, and when I booted the Wii version up I couldn't help but grin when I heard the first stage's music.
 
It's fun, so I should probably finish it.
