I have lots of ideas, it will be hard to decide on which one to stop, but before that, I want to finish Project Myriam, so first thing will be to finish the ending chapter first big scene, then bringing the game to the main ending point (meaning the point where the game will separate into most of the different endings).
After that, when I'll start working on all the different endings, I'll start working a little on the side on the next game, so that once Project Myriam is fully done, I do not end up with a big void of months before being able to share something with everyone.
But that's only some rough planning for now, I'll keep everyone appraised as I go.
