I think people didn't noticed last update here was in 2019 while his last post in pantreon was last month and look like his last update there in the game was in December. But I can't read what update since only paid member can see it.
So he must be using it here was a advertising page to his game only. How could I say. That could been seen as a demo and if want update probably people may go there and pay for it.
That is what I think. Even if he update the public version have a lack of more than a year between his pantreon versions and this one.
Maybe I could buy the game when he finish develop that but depends of where he going to sell that.
