Dev Update 2

Added more guidance with how to play the game through visuals and text.

Changes

• Added key icon above chests if player does not currently have one to indicate you need one
• Added tutorial images to controls menu
• Added text to main menu and controls menu showing what buttons to press to use the menu

This will most likely be my last update as I'll be starting a new game project. I will come back to make changes and fixes if they come up.
