So ok, I've played it for about an hour now and I can assure anyone who was one the fence about it, this is a really good game. At it's essence it is pretty similar to LostWinds in that it's a platformer with puzzle elements where you control your character with the nunchuk primarily and use the pointer to affect and manipulate the environment. Graphically it's not as vibrant and the environments are already starting to wear on me. However, the visuals are much more polished and artistically this is probably the best there is on Wiiware, along with World of Goo even though that game is artful in a completely different way. Think of it more like the Shadow of the Colossus school of thought, even though it in no way rivals that game.
The music however is excellent and everyone in the UK should really take a shot at that free OST. It has a very ambient sound to it and is filled with an atmosphere that's kind of a mixture solitude, sorrow and menace. Very effectful. Just that in itself bumps that game up a few notches and really immerses you in the game.
However, none of this matter if the gameplay sucks. But no worries, this game delivers here aswell. Mind though that I'm only an hour into it but so far it's been nearly flawless experience. The controls are surprisingly intuitive and the pointer controls are also much better than those in LostWinds (so far no waggle). So far the puzzles hasn't been too difficult but I'm sure they'll ramp up in challenge as time goes by. The thing I really like about it so far though is that many of the puzzles are bound to the artificial gravity engine and therefore there's some leeway to how you play the game, kinda like World of Goo although nowhere near as flexible. It all gives you atleast an illusion of freedom which is very satisfactory. In fact, the only thing that LostWinds had that this game doesn't is the freeroaming nature of it, even though the execution of it wasn't perfect in LostWinds really. So far this seems fairly linear but while my preference is openworld, it hasn't really bothered me at all so far.
Do note however that single player mode is not for people who are bad doing several different things at the same time. Things like trying the maneuver with your left thumb while holding the left index finger to glide and also the same time pressing the A button on the Wiimote with your right thumb while pointing towards the screen holding up a gigantic pillar with the B button... That can best the best of us. But no worries, in two player more the second player take care of the cursor and it then become a co-op game. And yes, player two can use blocks and fire balls and what ever to kill player one Double Dragon style so hilarity can ensue. Personally I like the "almost overwhelmingness" of the single player, it provides a challenge that inspires me rather than discourages me since it's my limits being pushed, not the game's and after playing through the game my ability to do several things at the same time will probably be improved.
The only negative point that so far discovered is that the game doesn't give you anyway really feedback when you grab onto things with your pointer. That does end up in a few cheap deaths where you thought you had grabbed onto a something only to have a giant pillar come down and flatten you. Some sort of on screen indication aswell as a slight rumble would have been nice. But it's not a big issue.
All in all I gotta say, this game is a winner. In fact, after Mega Man 9 and World of Goo, it's my favorite WiiWare title and I'm only an hour in so far. If you liked LostWinds this is a must have. If you like platformers in general it is also a must have. And if you like pissing of your little brother by throwing giant boulders on him constantly, this is a must have. Seriously, you should be playing this already.
