Despite some big bugs with the UI scaling and such (couldn't change settings for some reason), I enjoyed this one quite a bit. It was intuitive without being too easy, and your use of the visual/audio assets in combination with the narration did a great job setting the tone.
Though you can kinda tell the house was pre-made since it didn't always align with the grid in the most photogenic way. But I at least appreciate that you had to actually examine the environment for objects instead of having the key ones highlighted. Even if it's trickier, it feels more immersive that way.
The worst glitch for me was breaking the gun, which I think I did by aborting a reload. No matter how any times I refilled it, it stayed empty.
