I've played the demo and it's pretty dang fun. You're main objective is to saw a whole warship in to little pieces as you climb on it's side. It's fast paced and it makes you think a lot too. There are pieces of the warship that you have to use a bomb or a special "mojo attack" to get through. It reminds me slightly of dead space in that you must strategically cut the ship in to smaller and smaller pieces.
The game offered a bit of a challenge to me on the third stage of the demo and the ships it showed me at the end made for some interesting things to figure out (one warship was the half-life logo... no joke). It shows that this game was made by the same minds behind patapon and locoroco because of it's insanity. Seriously I couldn't think or crap like this in my dreams.
If you're in to puzzle/action games, or even if you're looking for something different, buy this game!
