Dungeon Hordes

You have found yourself trapped in a strange dungeon.  You hear a voice booming as you look around: ENTERTAIN ME, YOU PLEBEIAN!  HOW LONG CAN YOU SURVIVE THE HORDES OF MY DUNGEON!?

Roam around the dungeon, using your wits, points, and keys to survive as long as possible.

Controls:

• WASD to move
• Shift to buy an item from a pedestal or to open a door (requires a key)
• ESC to pause

This is considered finished.  I am looking for any constructive feedback as well as hearing about your highscores!

Almost all art except the mouse icon are CC-0(public domain) assets takes from itch.io or OpenGameArt.  Music is also CC-0 taken from OpenGameArt.

NOTE:  Tested to work in Google Chrome and Firefox!  Edge doesn't allow WASD
