Soul! Thanks for playing my friend, really glad that you enjoyed it!
The hazard system still tries to create blockages on the dead limbs, which is why when it is down to one limb it feels like it is slower. I left it in as a moment of respite so people could feel calm for getting as far as they did. Maybe I should have made it more hectic, apparently there is a bug where the other limbs resurrect themselves after a score of 8000!
