You can move it into any adjacent space as long as it is not occupied by another room. If you take the image above you could move the room that the character is in only to the right side. Moving the character offers more possibilities. You can climb ladders, teleport Matrix-like using phones and use objects like keys to open doors that block the exit.

Rooms can be downloaded to play offline or played on the web. I suggest to download the full version which has a size of 30 megabytes. Great addictive game.

It can be described as a arcade shooter. Your goal is to change the color of the background from white to black / black to white by shooting at colored circles that leave traces of their color on the background and part into two smaller circles of the same color. They split several times before they finally vanish from the screen.

The circles sometimes leave extras that you can pick up to get better firepower or become invincible with. Its one of the greatest freeware shooters that I ever played, if you would like tot take a look for yourself head over to binaryzoo.com. Enjoy and let me know about your score. I made it to 80% on medium difficulty in my third try :P

Update: Mono does not give you time to rest. The game becomes increasingly fast paced, and it does not take long before the first color balls start shooting at your ship.

Users who start the game for the first time should check the options to make sure that their preferred input method is selected. The game sets it to joypad by default, which you should switch to mouse and keyboard if you do not have a joypad connected to your PC right now.

The game gets difficulty at around the 50% mark, when bullets start flying left and right, and you are starting to spend more time evading bullets and enemy ships than concentrating on firing on them. Autofire is enabled which means that you can still throw out lots of bullets even without aiming at particular balls on the screen.

I’d suggest you try to eliminate the smaller balls first to reduce the probability that they will shoot at you or that you fly into them as it will get crowded on the screen if you do not eliminate the smaller balls.
