Navigate the city streets to get your patient to the hospital! To keep their heart rate up, collide with other vehicles on the road. Don't get their heart rate up too high though, or your patient will go into cardiac arrest.
Stay Inside The Box: The whole game takes place in just one screen, no scrolling or changing screens in any way is allowed.
Backwards: One or more aspects of the game works the opposite as would normally be expected: maybe the controller is reversed (left is right, right is left), maybe you win lives every time you die, maybe it scrolls to the left and your character moonwalks.
X Marks the Spot: The game involves something location-based, such as a geocache, or requires the player to go to one or more specific geographic locations.
May the (Web) Force Be with You: The game runs in a browser with no plugin.
