This game should have active weather..A rainy day can effect mood so it would it be a bad day/time to collect quoins or give a negative effect - on the multiplier ..sunny days could be better for quoin collection maybe give a bonus to collecting, but heat and cold would effect u in mood and energy..to combat the effects of heat and cold wear more clothes when its cold and.. wear less on warm days so u lose less energy on those days. Or maybe on hot or cold days drink something hot or drink something cold on the warm days to keep energy up. The wintry land already does this little. Why not global weather?
This was just a thought. :)
