Inspiration: Zelda with a ghostly twist. You made the most of your game draws.
Usability: This would be pretty easy to run as is. Keying the boxed info around the maps to specific areas on the map would be helpful, but their inclusion is a great idea.
Vibes: The double-booklet layout (clever!), retro maps, and 8-bit illustrations are fantastic. This is a classic NES video game in TTRPG form.
