Major bugfix
There was a bug in the games programming where it would create a sound file every frame the game was running which caused the sound engine to use more and more of the machines resources until it crashed and the sound would stop. This also caused the game to use a lot more of the RAM and CPU than required.
I have now fixed this issue so performance should be better than before and the sound should not stop after about 30 minutes of gameplay anymore.
Thanks for the patience.
