Wow this is really good! Here's my NO COMMENTARY playthrough:
I really enjoyed this-- loved your design choices. Some awkward slow-down when our character gets hit by an enemy though. And the opening cut scenes could have tighter transitions. But the exploration and problem-solving is top notch! I love the whole aesthetic and music too. Absolutely amazing.
Question: there's an area near the second vent that contains a locked box or something? Like it needs a key or lockpick, not a code. In my video it's at 10:49. Can it be opened in the demo? Again thanks for the wonderful game. Cheers!
