This was a really interesting entry! The textual imagery was evocative, even poetic at times. I felt deeply uncomfortable reading this (in a good way!): throughout the game I felt like an intruder, witnessing things they shouldn't be seeing. The ambiguity in following the narrative definitely helped with this. All the information was incomplete, and the imagery was so surreal that I questioned the reliability of the viewpoints I had access to.
I agree with some of the others that some of the text effects were overwhelming. They worked well, but maybe would have been better used for emphasis, rather than all the time. Some of the other effects worked well (the "I'm here mom", for example: I like how much it interrupted the flow of reading. Seeing that window come back again later in the game felt really satisfying, and gave those particular 'interruptions' their own character). The overall aesthetic was brilliant - the graphics you used really added to the atmosphere, as did the audio. Allowing the player to replay from the branching decision point rather than forcing them to restart the whole game was a good choice.
Often horror tries to overexplain, but I think you struck a great balance here. There's probably a lot to discover about what actually 'happened' in the text, but the ambiguity allows the reader to keep guessing. It feels like there are lots of dark themes on the periphery, and letting the reader draw some of their own conclusions really let these themes breathe. Nice job!
