It's harmless arcade shooting, pretty much the same tunnel running we've seen before, but frosted with some really beautifully crafted visuals. I love the snowy world and the feeling of the whole game. The animations are top-notch (the way the hero changes orientation) and the snow effect looks lovely. Many things are destructable too and the gameplay was easily adaptable. Steel wire was a great way of dodging from bigger enemies.
Still, I'm not that sure if I'll get it since I'm afraid it might get old after a few hours, so I'll look into first reviews to see if there's enough variety in the game.
