You need to add more ores in the mines make the 50 heart quest a 20 heart or 30 give legs to the monsters and give them walking sound also better eyes most of all better map system because its almost impossible for people to find their way monsters wont spawn in day and if torches are near also no spawning inside mini-map area lastly add more quests in big city and make the wall less ridicules i mean its a flat brick wall going from one side to another! at least put it all around the city and make the entrance more visible and bigger. that's my suggestion hope you like them.
You should replace the clay like monsters and put :Wolfs:Bears:Bandits:Eagles:and that stuff not big monsters with a gun sticking out of theyre brain :/
