Today I have updated the Heroes of Orn: Darkness demo to include a roadmap of what I have planned for future updates. This can be accessed from the Main Menu by clicking the 'Roadmap' button and it will also pop up automatically the first time you start up the game.
Here is the current Roadmap.
The Roadmap focuses more on big picture stuff, but balance changes, bug fixes, and other improvements will also be included in updates. As mentioned in the Roadmap, these details are subject to change in the future.
