Bodyville LD45 edition

In this game, you play as your immune system. You start with one macrophage (a creepy pink fella), and one lymphocyte (a blue star-like fella) that can’t make any antibodies yet. You have to control the macrophages so they can eat the invaders (green creepy things), and move the lymphocytes so that they make antibodies near the invadors’ paths.

The point of the game is to defend the cell structures from the invaders. If all cell structures are destroyed, the game is lost. There are waves of enemies; once you survive them all, you win the game. Each wave activates a spawn point in a different tunnel (a total of 4), so make sure to spread your macrophages and lymphocytes across the map.

Macrophages and lymphocytes can divide. Macrophages divide when they eat 10 invaders. Lymphocytes divide once, about a minute after creation. You can control every cell that has been divided.

When you start the game, the lymphocytes can’t produce antibodies. You have two choices: either move the lymphocyte so that it gets hit by an invader, or use a macrophage to eat an invader, and then share the genetic information with a lymphocyte. You can also move the lymphocyte so that it shares the genes with another lymphocyte.

Antibodies slow down the invaders upon collision. When any cell gets hit by an invader, it loses health. Macrophages gain health when they eat an invader.

Controls: Left click to select, right click to set a target. Select multiple units with CTRL+Click. Macrophages can go to a point on the floor, or they can chase invaders or lymphocytes. Lymphocytes can go to a point on the floor. Esc for main menu. WASD or move mouse to screen edges to move camera. QE or mouse wheel to move camera up/down.

That’s pretty much it. I had plans for invaders to mutate, but I ran out of time.
