New Version Up, Please Re-download

I finally got butler working, so I'll be able to create patches for future versions.

In this update, I added a few changes: New music, hints for unlocking ships, and a Retry button at game over.
To see hints, click on the lock in the ship select screen.

Note: I attempted to make it automatically fix the save file format, but you may have to reset your data file for it to work.
