Post Jam updates

I don't usually do this for Jam games, but I fixed a few of the more egregious errors that people had brought up during the Jam:

• Fixed the issue where a not serving a customer fast enough would soft-lock the level
• Fixed a graphical issue that would cause bun sprites to stay on counters after they were picked up
• Added some text during the tutorial that calls out what buttons you can use to attack/interact
