@Nazari has been hard at work on a new algorithm that makes your collisions WAY faster.
You can check it out by in this beta: https://testflight.apple.com/join/vvTykuD6
Please help us make this great by downloading the beta and doing everything you can to try and break collisions. That way we can release a bug-free version ASAP to the community at large.
Post any projects you make that show weird behavior in the comments.
