Vampire Fever is a billiard-like physics game, which you control your character "Viro" (instead of the cue ball) and try to infect the other creatures on the screen by touching them. The virus is very contagious, but it has one weakness: If two infected creature collide, they both heal.
As you progress, you encounter with different creatures (vampires, mummies, ghosts, electric demons, chocolate demons, and many more) and artifacts (barrels, bombs, slicers, trees, portals, etc.) which have different properties and physical behaviours, which call for new strategies!
There are three modes included: "Main Game" (with 120 levels), Challenge Mode (which include 6 arenas where you have to survive against a constant influx of enemies) and a Level Creator with the ability to save and load levels as passwords which can be easily shared by IM, email, blog comments, etc.
Click on Viro and drag the mouse to set the strength and direction with which to launch him, and release the mouse button to launch.
Use the buttons at the base of the play area to select (previously completed) levels, restart the level, pause the game (bringing up the Pause Menu) and set the audio volume.
