Dog's Run and the sequel Dog's Run Generations are simple running, jump and digging games where you play a dog searching for their lost bones. It's novel because of the focus on simple exploration, jumping and collecting gems. This do get a little more challenging when you need to press a button to swing across gaps (and solve more puzzles in the second game) but generally this is a very approachable game for really young players.

Play involves running around the large levels to find gems and hunt down your bone. Do to this you will need to jump across gaps. This is a little tricky in some places, but you can always try again if you fail with no penalty.
