Theme: Explorer
The player is an ‘Indiana Jones’ like explorer/tomb raider.
The goal is what you may expect: Get in and out of an ancient Mayan temple with all the shiny things you can carry! There are many traps, monsters, and paranormal things in there too, so don’t die.
I think I’m going to expand on this by adding a counter for extra gold, and change the ending depending on what you manage to get out. I’d love to hear your suggestions!
