this is the only horror-type game i have, and probably will ever have. i really really don't like horror games, but the cutesy art mixed with the unknown of what's next all while trying to farm has me hooked! i've barely made it past day one, since i get scared easily, but i cant wait to see whats next!
additionally, it would be awesome if there were weather events that could bring both useful resources but also different monsters too. moon phases impacting gameplay that either can brighten or dim the night gameplay could be interesting too, bringing different monsters depending if its the brightest/darkest night!
as for new levels, different types of farming is what id like to see. like farming in marshes or flooded lands, working with/in the water. this might be a stretch, but maybe even caring for livestock, defending your goats from a Chupacabra!
