I'll download the trial game for it.  I absolutely love the art style in the game.

Haven't played it yet, but I can't wait.

I just finished the game. Gameplay wise it's very good. Some of the puzzles can break your brain. The art style is beautiful but I felt the first half had better art direction with the forest setting. The second half was more typical platforming environments. It reminded me of the more industrial parts of Crash Bandicoot and Super Mario Land 2.

Storywise this game can go fuck itself. There's leading an interpretive story, and then there's this bullshit where they just throw 60 unconnected sets, enemies and ideas and say "Here, figure it out". It started off great also. The forest area with the kids attacking you from afar and the mysteriousness of them was just great. Then it just leads nowhere. The kids are never seen again and all of a sudden were going through a gravity factory. I do like interpretive stories. Braid's was awesome. The difference though is that Braid gave you the tools necessary to interpret the story to begin with. Limbo doesn't.

*SPOILERS AHEAD*

I mean between a forest, a hotel, a gravity factory, the kids attacking you, the giant insects and spiders, the appearance and reappearance of tires, saw blades, machine guns, you crashing through glass and the girl at the end you walk up to, how do you make heads or tails of any of it?

Well...played for about 30-40 mins and its says I beat 30%. lol...they weren't kidding when they said its short.

So far its not as good as Braid but mightly close. Braid music gives it the edge...too much silence here.

The first half is the better half. While the puzzles get more complex later, the general atmosphere takes a turn south. I really wish they would have stuck with what they were working with in the first half in the forest.

its craaazy one of my favourite games so far this gen at least :)

69% complete. This game is awesome. I agree that the atmosphere in the forest is better but the gameplay itself hasn't diminished. I suppose it's the feeling of accomplishment getting past the harder parts that is making up the difference for me. First half, I was saying how awesome  everything looked and now I'm saying how awesome I'm feeling after my brain is in a headlock for a few minutes. Either way I'm really enjoying it,  already 15 well spent dollars. Oh and again, dying has never been so fun.

Good to know, cause so far everything has been pretty easy... 30% in.

I need to try this when I get home later. I meant to download it yesterday but I was too busy.

Yeah at the point you are at I found it to be pretty easy. I don't really have much experience with this type of game though so what I deem "harder" may not be so for you.
