A lot of cool ideas that maybe need a little bit more polish. I managed to find a cardboard box and the exit before doing anything else, which mentioned I got away safely with the dice :) So maybe a global variable that tracks where you are in the storyline/questline is a good option?
Maybe add a few more bars of music? The short loop gets a little repetitive over time.
Congratulations for finishing on time, I had trouble with builds as well ;)
Since this was made in unity, may I recommend making a web build next time? People are a lot more willing to play a game if they don't have to download it.
