First of all, let me thank everyone of you for your amazing support with RPG Map :)
I posted a short roadmap to talk about the future of RPG Map. Don't worry, it'll be nice! You can read it here: https://deepnight.net/blog/roadmap/
Feel free to discuss about it below.
TLDR: release on Steam & rework completely to support all desktop platforms (Windows, Mac, Linux), no release date yet.
