Decided to make a new thread for this, since this turned out to be way more fun than I expected and I hope to expand it.
Adds sound effects when you die, kill something, level up, get gold, and lots of aethership things (turrets firing, enemy exploding, siphoning, docking, undocking, creature wandering in).
To install after you download:
1. Open package manager from the menu
2. Click "install".
3. Select sfx.mpackage.zip in the dialog that opens up and click "open".
Things that will keep it from working:
* unzipping it
* trying to install with the file called anything other than "sfx.mpackage.zip"
Feel free to suggest things that tickle your fancy.
