Dusted off my Wii last week because I saw some screenshots of this game and vaguely remembered I had some pointz in the ol' Wiistore account. Grabbed this and was instantly hooked.

It's a puzzle-platformer where you hold your Wiimote sideways and tilt it to tilt the screen to control water. At first you just control plain liquid water but you also unlock the ice and steam states as you progress in the game. The game includes the classic Metroid/Igavania concept of showing you unaccessible areas early on which you eventually reach with new abilities.
Game was devved by Curve Studios, who are also just now releasing Explodemon on PSN. Both these games feature music and sound design by RICHARD FUCKING JACQUES

Even though the puzzles are mostly very easy so far (I'm at the beginning of Chapter 3 of four) the game is just fucking charming and fun, and the bite-size challenge to get the collectables is really addictive.
All in all, probably the best water-based puzzle-platformer ever released for WiiWare. GET IT. 1200 points (which it is worth) or just pirate it, if you're
that kind of person Magus.
