This is awesome. Truly. Such a cool twist on the theme and a fun adventure throughout. The text on the statue for the hidden code made me think that it would take me somewhere else with no way to go back and that the key was some different secret, so I pointlessly didn't use the hidden code and wasted time. Kinda my own fault for wanting to explore too much haha...
Well done with the given time!
Things I'd love to see if you continue this, or even just want to flesh it out a little more: Make more things interactable. It'd be a great way to make the character's personality come through even more, as well as a way to drop hidden lore, or foreshadow the twist vaguely, or even just to crack more jokes.
Side note: WTF IS A 5 STAR DIFFICULTY IF SLAYING A GOD IS ONLY 4 STAR!?!?
