As captain of the Starship Mercury, your job is to save the galaxy from evil. Unfortunately, the Starship Mercury has become ensnared by...
The Bad GuysTM
The Bad GuysTM generated a vortex that shifted your starship into a matrix of alternate universes. You can only escape if you can find a route back to the normal universe.
Although the lights have gone out all over Starship Mercury, as you look out various windows, you notice the view of the stars is different. To find your way back to the normal universe, choose rooms that have the most realistic view out their windows. Choose carefully, as you don't want to get stuck in an alternate universe.
