Bjorn! Please be happy again! If your hobby doesn't make you happy anymore, put it down for a while, forever, whatever is best, tell the world that updates are on a hiatus, and then just bask in the glow of all the happy Dweller players on your forum. Above all, remember that you don't owe us anything, you made a free toy that we all play with, and we love it.
Of course, if you still want to keep at it, rock on, and if we can do anything to make it more fun for you, let us know. I'm not actually *good* at anything, so I won't be able to actually *help* make things better, but... ok, not sure where I'm going with that.
IMHO, if you just stamped the current release "Final" instead of "Beta," no one would know the difference. Even with the occasional bug, it's more stable and playable than anything Bethesda has ever released. You've done a great job, and if you feel like you're done, rock on with the real life. (Also re-release the version where magic was at %200 time and label it "Hard Mode." I hate losing so much, but let's be honest, that was a stable Roguelike that was exactly as unfair and abusive as the rest of the genre =))
PS: I donated so my request is that you relax and just hang out with us on the forum for a while. Or e-mail me or something. I dunno. Just smile a bunch.
