Nice game: kiki

I just finished playing kiki, a very nice game I recently found on Sourceforge. It's a 3D-puzzle with 23 levels where you should forget the distinction between up, down, left, right, before and after.

What is also great about the game is that it is open source (like all software on Sourceforge), which means it is really free. So you don't have a restricted version, no nagging to buy the complete version etc. And it is available for Windows, Linux and most other Unix-variants, and OS X.

There are more than 10000 free games on Sourceforge - well, some of the projects are actually libraries for developers to create games, but most of them are games.
