Your girlfriend has been transformed into a lizard: you go in search of a medicine to save her. The problem is that you're walking in a maze and that the exit isn't that easy to find. Fortunately you can rotate the labyrinth, but you'll have to be careful: you can also fall on spikes and in that case you'll have to start all over again!
Use A and D to move around. Press the arrow keys to rotate the window a quarter turn.
