Game: Micro Germs
A puzzle 2D platformer of the heart, where you are a germ trying to make your way through to heart into the brain. Red cells (Blueish dots) are food and white cells ( Purple goo) try to stop you. The speed and tempo of the game increases according to the progress you make. Also, your surroundings are affected by the beating heart. The ending might not be the ending you want, nor running out of bacteria isn't essentially a bad thing. P.S. You don't die, but your bacteria gets converted into white cell among contact.
True Colors: The game uses only the basic 16 colors: black, gray, silver, white, maroon, red, olive, yellow, green, lime, teal, aqua, navy, blue, purple and fuchsia. See color chart
Backwards: One or more aspects of the game works the opposite as would normally be expected: maybe the controller is reversed (left is right, right is left), maybe you win lives every time you die, maybe it scrolls to the left and your character moonwalks.
Approved for All Audiences: The game must not show any violence, not even cartoonish. Stepping on living mushrooms is off the list, as is killing any type of enemies, not even undead, though we know they’re already dead…
Bigger Picture: The game touches on a political, environmental or social issue.
