I remember playing this game called “Tower of goo” from Experimental Gameplay Project site while I was using Windows, it was a bit weird as most games from that site but very addictive. After some time I heard there’s some game “World of Goo” released and that there’s also Linux version. I was very glad to see such title for Linux, and that it got very popular in short time, because even though WINE emulator (yeah I know it’s not REALLY technically an emulator) gets more popular and supports more games with every release I always preffer native GNU/Linux games.
Not sure why, maybe because it said it went commercial and there’s only free demo or I just knew I’ll get addicted to it, haven’t actually tried this game till tonight. And I must tell you that I’m amazed! I downloaded demo deb package and installed on dpup. Demo only is 33MB, must be hell of a demo I thought, and it was! Game ran perfect on my PC with 1.8 Ghz and 768 MB ram with misty action music and smooth graphics. Demo version is totally playable, you can play whole first chapter without any restrictions, with levels containing some interesting graphics and gameplay, on top of that there’s strong feeling of addiction which makes you play for hours ’till your eyes grow big
