Every twenty minutes I want those targets to revolve around (change image to hittable state) revealing a target that people have 15 secs to click on any of the targets. We want the targets to 'drop' as they are hit.
Players will win turns in descending order, quickest to hit earns more turns. If another player hits a certain target, that target cannot be hit again by any other players during that setup.
The target states need to update as fast as reasonably possible since we are giving such a short window to hit the targets. After some period of inactivity from the browser window, updates should stop until the user clicks something again to reduce unnecessary hits on the server. A "sleep" state image will be displayed.
Need something that will fit in an area 500 x 130 pixels maximum. Images for different target states and background will be supplied later by our graphics designer.
