I love the atmosphere you've built here with the sound design, graphics, and lighting. Walking through the orbs of light to get the character's inner monologue was a cool idea and the story details there were intriguing; I found myself really wanting to learn more about the character.
I missed the hint for the combination order the first time I played; I got the order by process of elimination though so I didn't really mind too much. I think if you wanted to draw more attention to it you could place one of those dialogue orbs close to it.
Overall I really enjoyed it and I'm excited to find out what happens in the next chapter. Congratulations on a great game jam!
