You have to monitor a simulacrum of a heart and watch the oxygen-depleted blood get pumped to the lungs, and from the lungs to the rest of the body via the Heart. Use the left mouse button to place white blood cells to attack viruses, and the right mouse button deploy shockwaves to combat cholesterol blockages. See how much damage you can prevent within the time limit and set a high score! This game includes a colour-blind friendly mode accessible by pressing [C].
The game is a 3rd person, retro 3d physics plat former. The player is a frog who must save the last of his kind (tadpoles) spread across the levels he must use his tongue to latch on and navigate through the level with. He must also not dry out so the player must be quick or return to water regularly.
