Thanks for playing!
I agree about the stuff flying off – Originally, I wanted to allow stuff to break off when you smash into things too hard. So there is a break force proportional to the object’s mass, which works OK when you’re small. But when the ball gets big (and the turning forces increase with upgrades) stuff on the outside starts to experience huge torques. This is why it’s nearly impossible to pick up small items on the outside of a big ball (small mass -> small break force and large radius -> large torque), which was kind of unintended.
I tried turning off joint breaking completely and I think I like it better TBH, so I may publish an post jam version some improved/fudged physics.
