I though this was great! Definitely a unique way to play. The controls were perfect for what you were trying to accomplish and the rag doll graphics were really good. I almost cringed everytime I accidently ripped the guys tendons apart, ha.
I agree with the idea of putting sounds in. Also, it would be less repetitive if you made different scenes (indoors, jungle/tree, cliff, etc.). All in all though a really well done little arcade game that one can tell you took some time on.
Thanks for making it!
