Just a bug report (taken from 0.7 trunk version):
I know that the custom skins were made for more freedom, but it will result in a lot of ugly skins. There should be an option to see only default (0.6.2 pre-made) skins with 0.6.2 colours (the most similar if somebody 0.7 ones were out of scale, or the same if he had colours in 0.6.2 scale). D: I really don't wanna watch tees with mad skins.
Another 0.7 strange visual (high-resolution link, it's more visible there what I'm talking about):
There should also be an option for 0.6.2 nice connected pain and happy eyes, alongside with normal feet size and outlines.
Probably a lot of tees doesn't like the spaced eyes (for me it's not a problem, I can change graphic files, but not every tee is capable of that (despite the fact that it's a bit of work)).
About the physics - in my opinion, current are good. It's a game, and things like hammerfly and hookfly are too much fun to give them up.
