So far so good...
While trying to be unconventional with my theme I didn't make it easier for myself. I want to stay as true as possible to the original Rogue, but wide open landscapes don't really translate well to dark and narrow dungeons.
So I made a HUB-screen. You can travel from city to city, which represent the levels in Rogue. When entering a city you'll get into the "dungeon" with different rooms. You can exit the dungeon with your horse, to return to the HUB.
Enemies are not added yet, and the objects you can interact with have no effect. But it does something!
