The game idea I went with for “Tiny World” was a game where you play as a bacterium, surviving against other bacteria.  The first day I got the main engine down and added the player and other bacteria.  So far you can attack by swimming up to someone, holding the mouse over them, and pressing space.  Size affects damage.  Right before I went to bed, I added toxins, which are clouds of stuff you can leave to confuse or damage other bacteria.

For Day 2, I’m hoping to add the following:

-Chemical dart

-Eating other bacteria heals health

-Armor and spines

-Flagella

-A point and upgrade system for making the above upgrades cohesive.
