Fun, I love a good Katamari-style game. The collision physics on the items starts to turn it into almost a pinball game once the speed picks up, that might be a fun idea to experiment with further.
The pinball movement was a happy accident \(^o^)/ I think when Fuumiko's collider touches another object, there is a small amount of rotation applied due to drag and at high speed that makes everything go wild.
