World of Goo
I downloaded the demo of World of Goo from Greenhouse. This is the fist game from independent game developer 2D Boy. The basic idea is that you have these goo ‘globs’ that can connect to each other to reach a suction hose that collects them up. The un-used globs will be sucked up into the hose and each level has a minimum number that you need to collect. The game is based on realistic physics, so if you’re building a structure it’s going to bend and sway depending on how you build it.

If it sounds weird, it’s because it is. This is a game that is definitely high on the bizarre humour ratings. It’s essentially a puzzle game, and it gets progressively harder as the levels go on. You also get new types of goo, such as ones that you can re-use.
Also, each level has an OCD award. You get this for either collecting the maximum number of globs or finishing in a set number of moves. I’ve only managed to get a couple of these, it’s pretty hard.
