Here are the little things that bug me in the game.
Floor - A floor tile always occupies the whole tile while a wall occupies the middle of the tile. This makes making a building have excess wall outside the side walls. Making the have half tile sprites might help make building look good.
Hoe - Steel tools can be stored in wooden boxes except the steel hoe. It makes the steel hoe look like a clutter when laying on the floor while other tools are stored on wooden boxes. Make the steel hoes storable to wooden boxes and carts like other steel tools.
Small Pit - A lot of items can’t be thrown to small pits making it hard to manage the clutter issue. Add more items that can be thrown in the small pit.
