Simple can be smart, and this indie puzzle game is simply gorgeous to boot. Play as a little monster who just wants to build bunches of snowmen (and snowwomen!) by solving clever, tightly designed levels with rich atmosphere that will suck you in no matter what the weather is like outside.
I think we should have some bonding time. Chemical bonding, that is. In the clever chemical puzzler Sokobond, you're given a handful of atoms and the task of them joining them all by pushing and chaining them together. Like Sokoban puzzles you might be familiar with, you don't have much space to do it all in, so you've got to use the splitters, bonders, and rotators provided. Even if you don't give a hoot for chemistry, Sokobond is still a very accessible puzzle with easy-to-learn rules and an enjoyably element-ary design.
Wanna see a crazy experiment in game design? Experiment 12 is a collaborative game created by twelve developers, with each level building on the story set by the previous ones. You wake up in a testing chamber, but it's hard to tell where you'll be headed from there, as each level chapter introduces a new puzzle or platform element for you to tackle.
