Great "game" !
Some features that would interest me :
- non mobile joints (to make fixed angles with bones)
- to be able to edit (add or delete or move joints, bones, or muscles) after several steps (generations). This could be useful to first learn "basic" behavior (like walking) to a quite simple but secured pile of bones, joints and muscles (secured in the sense they cannot fall easily), and then remove or add components so they are more efficient.
- to record data in a csv file, data like the best scores over time, or all scores over time ...
- and would it be possible to have a look to the configuration of the "neural net" of best creatures (as a list of parameters for example)
