Fortunately, the game itself is nowhere near as complex and difficult as its history.
Warehouse is a puzzle game that consists of 23 levels of increasing difficulty. You begin on the stack of crates surrounded by a dark outline, and are trying to get the box marked "E". The numbers on the crate stacks indicate how tall that stack is—you are looking down from above.
To move, click on any adjacent square. If uninhibited by other crates or stacks, your stack will fall over in that direction and will land where you clicked. You may also move to any crate or crate stack that you are adjacent to simply by clicking on it.
Analysis: An excellent puzzle game that is perfect for coffee breaks. The music loop gets tedious quickly, unless at a low volume. Thankfully, it defaults to the off setting. Interesting. To turn on the music, click on the loudspeaker. "Undo" is a useful feature, as opposed to having to reset the entire puzzle, which can be done by going up and then down a level. The level up/down buttons are also useful for when you are really stuck, as there does not seem to be a "help" button.
Strategy: Early on, there is often only one route. It helps to think through the problem backwards (i.e., how can I get to the exit? how can I get to that crate? how can I get over to there?) until you get to the start square. Later on in the game, keep thinking one step ahead: If I knock this one over here, I won't be able to tip that one over there. Also, if you want to tip something but it is blocked by a stack, tip the blocking stack perpendicular to the way you want to tip the original stack. Beyond that, good luck!
Update: It appears this game is no longer available on the Lightforce site, so I am mirroring it here for posterity. If the rightful owner of the IP objects, please notify Jay at the email address in the sidebar and we will remove it.
