Just an update, I was able to get a hold of him finally and all I did was to wish him well and hoped that he was doing fine. He replied to thank me and to wish me well too. I didn't pry as to why the game suddenly vanish. I don't feel that it is my place to pry, even though I'm a Patreon.
Now, before the trolls come on here whining and bitching about how Kross is a scammer and milker, as children do, Kross never charged me a monthly fee on Patreon. The only time I had to pay was when I first signed up to get the latest version of the game. That was almost three years ago. While I'm disappointed the game seems to be abandoned, I don't feel that I am entitled to answers. Kross is his own person and as far as I'm concerned, he can do whatever makes his life better, and if the game isn't part of that equation, so be it.
