Those crazy Cosmic Bugs have infested our ocean - and they’re making a huge mess! It’s up to you to clear them out and restore our precious ecosystem!
Water Bugs is controlled by single clicks of the mouse/pointer button. Move the mouse to position your harpoon, and then press the left button to release your shot - the harpoon automatically goes in the right direction. If you want to try and get the direction right too, click the right mouse/pointer button instead.
Some optional keyboard access is required for entering your name (although this is only required once, and you could just accept the default name) and pausing the game with the Escape key. It is possible to play the game without using the keyboard at all. Accurate timing is needed to hit the targets, but the actual game does not have a time limit.
