Stickman Escape Out

Stickman Escape Out is a tunnel-digging game where the route is something you create rather than something you find. You drag your mouse to dig through the ground beneath a prison, carving a path in whatever direction you choose, and along the way there are keys and gold to collect that make the dig worth taking the long way round. At the end of the route a vehicle is waiting to take the escapee to a better life, so there is a specific destination rather than an open-ended tunnel. Digging the right exit is the phrasing the game uses, which is a fair warning that not every direction you can dig in leads somewhere useful.
