I'm sorry for my absence and lack of updates to the game, the forum and the site. Dweller is not dead, it's just that I have very little time to work on the game. I've had a super busy spring and summer work-wise (yes, I have a full-time job that puts food on the table) and very little spare time to work on Dweller.
As you may know there's been discussions on the forum on how to improve the UI of Dweller. During the few hours I've had to spend on Dweller each week I've worked on a new UI. It is not yet complete, but it's starting to shape up. If you're curious you can check out the desktop version alpha here.
