Thanks for confirming what I was already thinking. My post was a reach out to Sir D and the co-developer (reached out to them directly as well) to see if Sir D would respond with any more word on the status of the game since testing started. Your response was the first here. The co-developer resonded that the games he was developing had taken priority and that Sir D should respond about Radiant since he is presently developing it separately from this co-developer. Kind of a shame because the co-developer's games are pretty well done showing the tallent that developer has and was bringing to Radiant during the "Co-Development" processes.
I guess we will be stuck with what you and I have figured out may in fact be the case. Sir D has a responsibility to the game and fans of the game so it all falls on him to address our, and all fan's concerns about production status.
Oh. And I have also stopped funds to Sir D pending more positive action with Radiant. Had done so before posting my comment about selling this game on itch accordingly.
I suppose we will see. Eventually. One way or the other. In the mean time I will continue to enjoy Neko Paradise as updates are still coming out for it.
