Quite a mood and surprising ending. Very good sound design, and change to red color palette at the climax was great.
Minor suggestions:
- Complete silence inside the house did break the immersion a little. Perhaps silent, muffled ambience would be a good addition.
- Outdoors sound, on the contrary, could be a bit more silent and subtle. This way, transitions in audio would make the surprises even more dramatic.
- Amount of text could be reduced in order to give room to the ambience.
Awesome job. I look forward for more.
