I feel like this might be something that would be low on the priority list, like something to slot in once the whole story/development is finished. However I feel it would be worth having Cruel Serenade, the chapter one map and plot eventually ported into Guttertrash once everything is done with. Granted, new content and finishing the game would be much preferable but hopefully once that milestone is met, having the whole story be a seamless experience would feel great.
I admit I felt a bit of whiplash for like the intro flashback part of the island for Guttertrash, I was like, did I just miss something?
I look forward to your future development. And a toast to your success
