Wow! Thankyou for such great feedback! I certainly need to clean up the crawler script - it's been deferred maintenance for... 3 years? I'll need to add a few options for things like move/rotation speed. Was the increased volume on the end boss or just a random enemy? I think I had the mix settings different in LMMS for that song. I'll need to see if I can replicate the OOB issue, not sure what would cause it, but I have an idea.
Thank you for checking it out!
