Thank you! Ya the audio multithreading would've fixed a lot of the glitching with the audio. The mud covering/digging is based on cellular automata kind of like falling sands/powder game.
I kind of ran out of time for what I wanted to add for the tasks. I wanted to add a "bury N bodies", "take out the octopus gang house", "check out the expressway" and such as a second objective list after "The Molt".
