Yup, its not abandoned, I was thinking of abandoning it but decidet to just develop it slower and cut some content.
Final map won't be much bigger, I plan to improve it so it doesn't feel so empty in the final version. The problem with stamina should only appear at the beginning , after distributing skill points you can increase the amount and regeneration of stamina, I am planning to make character development even faster.
About running across the map, waypoints are bugged sorry, I will fix this and I am planning to add an item that can instantly teleport you to the village. Waypoint only heal ~70% of hp, maybe I'll change it to 100%.
More sex scenes, more quests and more enemies, yes, it's planned. I am also planning to improve h-scenes but in the further term, after 1.0 version probably.
