Based on the original by oopsurdead.

V4 has added children, death, generations(will be viewable in V5), Recessive Genetic Disease(currently represented by protractor setting), less random mutation, a population-controlling border, and a few more smaller things. Also, beside the current version is an almost unedited version of the original, so you can compare.

Genetic Disease can lay dormant for up to 2 generations before it is gone, or appears.
Each circle can have upto 3 children, though may have 1, 2, or in some cases none.
Death happens along with the final child.
Generations are only sometimes shown, and in the download will most likely disappear completely, so sorry but no generation count for now.

NOTE: Each new child, and the first generation, will have about 4 seconds until it can have its own child, and the same amount in between each child.

V5 WILL HAVE: Gender, Generation counter on each individual circle, a new additional disease, and Inbreeding counters.

EDIT: V4.1 Release Patch- Collision mishap fixed
