Yendor's Heart

A VERY little game I made in January 2018, inspired by Robot Finds Kitten:

"Your best friend, Sir Rodney, went on a dungeon crawl last week to retrieve the heart-shaped Amulet of Yendor for his wife as an anniversary present...
In his excitement on clearing the dungeon of monsters, he forgot to grab the heart-shaped amulet!"

Notable Features:
- Thin walls!
- A rideable mount!
- An obtainable item!
- Multiple dungeon floors with stairs!
- Easter eggs!
- Plot!
- Glorious 15x15 pixel resolution!

Controls:

Arrow keys: Move up/down/left/right

Enter or X: Start the game, use the stairs, pick up an item, ride the horse

Riding the horse: Horse can easily bypass some insurmountable obstacles. As such, Horse will help you easily traverse the dungeon. Horse will also keep walking in a straight line. You do not need to urge Horse to move faster, but you can. You can dismount Horse anywhere, but you must be standing where Horse is to begin to ride.

Walk into the door to leave the dungeon. Otherwise, obvious exits are where the gray floor touches the edge of the screen.
