Great submission, lots of polish here that can't be ignored. I played through a few times but the actual win condition doesn't make much sense to me. You have to collect bones very quickly in order to win, if I understand correctly, but in my experience, the bones don't want to stick. I could roll over them slowly and it still felt like there was only a small chance they'd stick. The ground slam didn't help much either. Not sure if this could be performance related but performance was pretty good for me. Despite not being able to win, I did check out most of the level (I think), and really love the atmosphere.
Thank for playing our game! General tip would be to pick up smaller bones at the beginning so that it's possible to pick the larger bones (worth more point) toward the end. Similarly to Katamari, larger items are gated on picking up smaller ones. There is code to make it easier to pick up objects if moving faster (ground pound), but it is short-circuited by the "distance" check, so it doesn't help much :p oops...
