Theme Hospital

Level select:
Start the game from the command line with hospital -L<level number> (for example hospital -L5) to begin on that level.

Place several items at once:
When you place an object in a room (a bench, radiator, plant and so on), hold Shift while you click to place five of it at once, or hold Ctrl to place ten. This is handy for the benches the patients wait on.

Remove litter and vomit quickly:
Pick up a bench, fire extinguisher, radiator or drinks machine and put it down on top of the litter or vomit. The mess disappears at once, and you can move the object back afterwards.

Best VIP rating:
The best remark a visiting VIP can give is "What a storming hospital. When I'm next seriously ill take me there!", which comes with a cash grant of $4,000.
