Version 0.28 of Sol 0 has been released! Head over to the download page to pick up the latest version. 0.28 is NOT backwards compatible with 0.26. Existing colonies will likely not load correctly. However, you won't lose the number of terraforming stations that you have completed, so your progress to unlock the last level will not be lost. I don't like losing backwards compatability, but with this update there were a few changes that had to be made. Here are a few of the changes in 0.28:
Random level generation has been added! All the old levels are still there, but a 'landing ellipse generator' allows random levels to be created. It's not perfect yet, but it is pretty fun and adds a lot of replay value to the game.
Fixed a bug where astronauts would not build when arriving at the build location.
Levels load faster - there was a bug where a section of level loading code would accidentally run up to 40 times...
