We have been working on the 1.3 update for SimplePlanes for the past couple of months. It has a ton of new features, which we are not quite ready to discuss. The Steam Beta is currently in progress. If you want to join the beta, PM me on reddit.

We plan on releasing SimplePlanes 1.3 on Steam (PC and Mac) on December 17th. The mobile release will not be available until probably late January. We are still not exactly sure what features will be included in the mobile version, because not all of them will work for performance reasons. We will keep you updated in January when the mobile release will be finished.

Edit: If you bought the game on Gumroad, you will receive a free Steam key.
