I really like the idea of configuring your robot! Cool concept! The different configurations that I tried didn't feel that different so perhaps making each point have more impact on the given attribute would be good.
I agree that some configs you can't really feel a huge difference unless you put almost all the points into them. I too was thinking about changing the total to 10 instead of 20, and making each point have more impact. Anyway, thanks for playing, and for the feedback!
