Brandywine

How it works: The world is 256 by 256. You see 16 by 16 squares on a tablet or computer, and 8 by 8 on a phone. The window recenters on you when you reach the edge. Trees, rocks, log piles, clay pits, wolves, hills, and houses come from the shared world. A wolf has 1 to 10 hit points. Click it to strike. At 0 hit points it disappears and you take a wolf skin pelt. Click a house to see what the villager will trade. Click an item in your pack to drop one on the ground, or eat an apple to heal 10 hit points. A drop leaves a sack. Sacks do not block the way. Step on a sack to take what is inside. A sack goes away when it is empty. Other riders show up only when they are inside your window, so you have to travel to find them.
