While yes, it was a very short lived idea, the 1.5 update of DF isn't going to be made.
This decision was made with help from @HeisenbergusS (thanks!), as I should be focusing on my other games instead of updating this one.
As he said himself, some things can remain as lessons from the past so mistakes aren't repeated in the future, and I believe that to be the case with this game.
It simply isn't worth it to waste time on this update instead of working on my other games, it's a bad habit of mine to always update old games if they're bad, which I won't do from now on (unless it gets to like, Tubturn 2: EEN level)

The page will get a graphical overhaul possibly tomorrow, which will be the last thing I'll do on this gamepage.
See you then, and hope you understand and aren't disappointed!
