Only just found out about the game being put on hiatus, it sucks because this is suck a good game, doubly so for me since this is now the second amazing AVN that I only recently discovered that's stopping development, there is hope that Atemsiel will eventually come back to Stormside and I hope that you do Atemsiel, I get why your taking a step back I understand and empathise with your plight to find motivation now that your passion feels more like work, taking a break will hopefully do you some good mentally, and as I've seen others mention, I wouldn't mind if Stormside became a more linear story without the branching paths that would certainly take a load of your back but would also change the game a lot from your original idea which would also suck, potentially working on only 1 branch at a time could help you get into a better headspace and workspace and allow the story to reach the end point (or one of them at least) which in turn might help with the other branches making them slightly less taxing ultimately more people helping you would be ideal but I guess that cant be helped right now, i would offer to help if I knew anything about Ren'py.
I do hope you don't completely end up abandoning or forgetting about Stormside, it is fantastic and if I remember rightly from the patreon post you did say you also like the characters you've made, I hate seeing a good game die so lets hope you can rekindle your passion for Stormside.
