Collision based on the actual mesh is needed. The current method does not represent the hands, and often does not reflect the actual humanoid.
Nicer scaling, and ability to randomise that, for the humanoid's various parts would great.
Better seed generation that doesn't constantly increase would be good.
Currently, typing into any textbox does not ignore shortcut keys, making a seed including 'i' impossible.
The ability to test the creature at path finding: a obstical course where the creatures have to get to multiple places in order.
- Could register 3D distance as well
Dynamic starting height. Not all fall the same distance when they are dropped at the same height
