Read the in-game manual by pressing F1, the game is quite complex!

The vi-controls are now available, and you can also simulate a middle click by using CTRL+left click!

For Linux users:

• You need ALSA audio and SDL to run the game. (You most likely have them already installed)
• If you get stuck and can't click anything, press ESCAPE and you should return back to normal
• You can also run the windows version using Wine
