Thanks for the kind words. Development has been really slow the past year but I'm still working on it. I've changed a lot of things internally (i.e. UI) and I still haven't finished the transition to the new code, so it'll take some more time until the next version.
The only issue I'm aware of is that on Windows the game crashes when quitting, but this shouldn't affect any of your savegames or sandbox schematics (crash happens later in the code). Have you found any other bug? If yes, I'll be glad to hear it and see if it's already fixed or not for the next version.
Sorry for the delay on the update.
