Look, it's just a simple two legged buggy stick-man. You should be happy about that we even have two of these things. Just because it has bad controls, and ragdoll-like movements, you just can't expect it to be fixed because one person doesn't like it out of a majority who wouldn't mind, but also couldn't care less.
I actually like how stickman movement is so buggy, it makes it fun to play around with. You can jump really high and go really fast and through things because of them.
