Hey Keyband, good to have you back! I saw you posted a couple games, looking forward to playing them soon!
I think quests will be a good idea, currently the game sort of has quests - when it or the farmer suggests something you should do. Later in the Adventurer/Dungeon side of game I think I will have more formal quests, like rescuing trapped miners from monsters, for example.
Aside from that I haven't given the sequence problem much thought, I just updated the game with some massively cleaned up code, so from here, I'm gonna go back to brainstorming about the sequence idea and see what I can come up with.
