Thank you minic-h!
Our composer HexenMapper did a really good job with both music and sound effect. You can check more of his work here: https://hexenmapper.itch.io/
You are right with Imphenzia! I watched his video few months ago and I practice back then a little with car models, but most of a job was done from reference images (Google: "low poly cartoon car")
This bug is known to us, but I thought that we fixed it for good🤔 (it was much worse then this). I guess in right circumstances it comes back. Good job at breaking the game ;)
