Double postah!
The game is a simple 2D/3D Platformer. It's basically old school Mario with upgraded graphics and less options on what to do. What I mean is that you can only Jump and Grab. No super powers or whatever to deal with enemies. Kinda like Sonic, I guess, how you just jump on enemies to kill them.
It's very puzzling. I often get frustrated because I can't solve a puzzle. LBP encourages multiplayer, since it incorporates it into the main story. So hopefully you have Wi-Fi or something so you can get the goodies.
The real point of the game is creation. That is what it is all about. Create stages to your liking and share it worldwide. So far there have been a few good, original stages and it's sure to grow soon.
Bah, I can't explain it. You guys just have to play it. I assure that you will at least giggle playing this game...giggle in a manly way.
