This game was, funnily enough, going to be made into a CYOA-RPG (Chose Your Own Adventure RPG)! Also, Inventory, keys/doors, levelling up and stats are all implementable! In fact: Heres a (very minor)spoiler: Later in the game you meet other letters! They join your party, which increaces the overall stats you have, as well as giving you a new, more overpowered(yet costly) spell for each Letter!
