Terraform, Plith, Vizati
Terraform is a turn based puzzle game set in the future. Alter planets by using 13 different tools and four weather conditions. The planets themselves are made from 14 different hexagon types ranging from water and forests to lava and deserts. Each of the four weather conditions have different effects on the planet. Create hurricanes and forest fires that impact the planets in their own way. Play through the story of 85 different planets and even more extra challenges. Also features a robust level editor to create, share and download new levels for endless replayability. Solving planets faster and with fewer tools gives you a Terraform rating that you can then upload to compare with others online.
Plith is an indie puzzle game for Windows, OSX and Linux. It puts gamers in a spatial setting, where they have to manage several puzzle elements (mostly gears) and must make quick decisions which can simplify or complicate their path to victory.
Vizati is a puzzle game that will put your mind to the test. You have to rotate a magical cube to connect (group) the little vizati stones by color and figure out the best way to do it with a limited number of rotations/moves. You can play the Story Mode and follow the story between Julie and Peter who discovered the Vizati cube, or play the Arcade Mode, which is a rawer, faster and even more teasing mode.
