Hey Sean, thank you! The day indicator in the UI decreases each time you go back to the village, and if it reaches 0 you die because of the curse. We wanted the villagers to give you quests and rewards, but we didn't have time. So the only thing you can do at the village is to talk to villagers and recover HP by walking. We also wanted to add a boss (the evil thing that is cursing villagers and travellers like you) after descending certain number of floors, and win the game if you defeat it, but didn't make it in time either. And of course, more items, weapons (ranged, wide, bombs...) and enemies with different behaviours and attack types. We may update it in the future if people like the game :)
Thank you all for all your words and for playing, even if you didn't leave a comment! :)
