The minimap is a result of my over ambition... I imagined map to have location of NPCs to follow, and all sorts of things just couldn't complete it in time.
The black npc appears when you accept a scam quest, (basically you get scammed and loose a heart) many suggested to type it up for better understanding, I updated that...
The space bar is something new that I am hearing, I'll look at it surely...
Thanks for pointing out these things from my game really appreciate it :)
