This got complicated super quick lol.
What
jfmherokiller said about the content ownership problem sounds like something exists from the beginning. But they only stopped advertising the port after June as you said, is there a dispute raised only recently?
Were they even planning to do the port, but have to stop due to this dispute?
Or it's never in the plan, just some false advertisement shit since the growing dissatisfaction with existing engine? And only retreated when being caught?
Or it's a totally different reason, like the guy who said to be working on the port no longer plan to?
Not sure about Raising Popularity since it's quite niche, but the port should definitely make this a better game.
Also Just checked their page, they started to advertise their Patreon Cheat (along with other privilege), just as I suggested earlier. Not sure are they watching here regularly.
Yeah they are not advertising the port anymore lol.
