Wow, loved this! The opening scene was really compelling, I particularly loved how the dream ended and the audio transition into the first chapter - perfectly impression of the off-kilter feeling of leaving a dream. The interactions with the fish was also surprising and intriguing, and I would be really excited to unravel their mysteries! I also like the base you establish by the end, having a room for listening to music was a great choice, and I could see myself hanging out there a lot and listening to these jamming tracks.
I don't think I have much feedback on what exists so far, and would be excited to continue playing if you publish more of the story! Great work!!!
