As someone who has been keeping close tabs on the developer ever since Mutant Mudds jetpacked into my heart, I can agree with the sentiment here- Renegade Kids is very jumpy about their IPs. It seemed, to me, that the lukewarm receival of Treasurenauts was met with some more development time to flesh out the content and concept, but instead they've abandoned it for Xeodrifter- which, mind you, sounds like a cool idea, but the discussions of length and the lack of progress on Treasurenauts make me skeptical. I'm not a fan of the episodic release schedule of Moon Chronicles and I hope this doesn't turn out to be another half baked idea like Cult County.
My faith in the developer who made one of my favorite 2D platformers ever is being tested.
