Back again after a while. Found some bugs. Game's still fun, though.
Going out the door from the ruined building in Nexus Forest North makes the screen not scroll. Going into the magic door gives an error "Failed to load data/Map119.json". That file doesn't exist in my folders. Windows version.
Exiting the dungeon with locked gates (NE of castle, from the cliffs at the beach) leaves me stranded in the ocean.
I kind of want to use the feature to turn off followers on the map, but they keep reappearing after various events.
I'm not sure why you can buy both tonics and stimulants for those rare coins. One is just better value than the other, and for a limited resource that feels kind of bad.
