Thanks for playing and your inputs!
I tried lot of tricks to make them spawn away from the head but if you go directly toward where they spawn you can still catch it. I debated not colliding with them would be a solution but it could suddenly make them enemies a lot more deadly
I put engine level sleep for 20 ms (or impact) and that could to be what stops the music from playing, but sometimes it keeps playing. I have not figured out what causes the issue in web builds.
