Fixed that bug! I believe it was because my web build did not have SharedArrayBuffer support because the assets are actually preloaded.
Hope you give it another try! :D
These are some great suggestions!
I was considering adding different plane behaviors but I didn't end up doing it because of time constrains...
I did try and make it get harder, but I never really tested it to see if it's working. Though the blue ones are the easiest, the green ones are the middle, and the red ones are the hardest.
