Lunar Mouse House

On one level, you could argue this is like a cut-down version of Starship Eleven - it's the same "navigate using your thrusters through tunnels" idea, with the same gravity-drifting physics as Monkey Lander.

But while Starship Eleven has all that tricky obstacle-dodging and shooting, there's only one real challenge in Lunar Mouse House: picking up rodents and transporting rodents in their giant outer-space exercise wheels (or maybe it's just a very small spaceship - who knows?).

Up, left and right arrows to thrust in those directions.

The spaceship can withstand a few minor impacts, but your mouse passenger is much more delicate (and can still lose you a life), so be careful when it starts swinging around.
