Its a really polished game! I like the art style and the relaxing environment! I played for a long time and noticed an issue with the quests. They don't get completed for 100 items for some reason. Apart from that, it's a brilliant game which you should definitely expand upon!

You can expand the game in quite a few ways. For example, you could add a few enemies such as boars or wolves that would attack the villagers, so a new working class of guards would make sense that would patrol the map and hunt those enemies!
Another addition could be adding bridges to connect isolated parts of the map.
