You’ve probably heard about this game and passed it off as some kind of strange flash based thing not worth bothering with.
So why are we bringing it up. Because it’s wonderful. – http://2dboy.com/ – Go now and get the demo! It gives you the whole first chapter for free which gives you a taste of this great game.
Can’t be bothered and want to know what it is first? Well it’s a puzzler, where you control globs of goo, sticking them together to solve puzzles. In fact it’s a lot like lemmings as you use the goo to get across gaps to rescue them or solve puzzles to get to an exit. The difference being you can’t give the goo powers (although they do come in powered flavours) and it’s physics based. So stop reading and go waste an hour on the demo. You WON’T regret it.
