It's interesting so far, I had issues with the middle character staying dead on quitting via the blue gem, and think there should be different height landmarks to help navigate, or a larger minimap. Seeing a tall tree, mountain, or building rooftop would really help with remembering where you are. Otherwise, looking forward to more on it
Ability to map things is high on my priority list, but it's a coding and structural challenge. Having companions go missing after being stripped is an intended big part of the game I didn't quite have time to fully finish. You'll get everyone back if the party is wiped out, and in future releases there will be scenes that require for your friends to be lost.
