Thanks for playing! We were definitely a little hesitant about how to approach the vent section. We wanted the player to feel claustrophobic and disoriented, but not to the point of frustration. At one point we considered adding a faint green glow to guide the player so it wasn't so confusing... but we ran out of time haha.
We tried to explore a concept by showing and not telling, so it's great to hear you found the story effective!
