Finally got it to work! Very atmospheric. The sound design really adds to it. It was short enough that replaying to get different endings didn't feel tiring.

The endings could be a bit clearer. There are 2 endings that end with a message encouraging you to find the other endings but the ending where you do kill everything doesn't give you this message, I think? I kept backtracking and even restarted to see if I missed something and I'm wondering if that's the case or it really ends with the voice thanking you and leaving you to kinda just wander around
