I like the color palette and the pixelart style!
At first I did not understand what I had to do exactly other than just exploring, then out of curiosity, I interacted with the katana to find out I can choose the fate of the streamer as the chat. I could never predict that and made me laugh when it broke :D
I think the balance of the amount of the text is nice. Games like these tell too much story most of the time, which kinda kills the fun in my opinion. I never felt bored while reading in this game so good job! There is also the option to just skip the texts if desired so I can tell a lot of time went into game design.
Some polishing like a map of the house, adjustable UI to make the text bar/dialogue smaller/bigger, particles and some animations would be cool to see. It would also make the visuals more interesting to look at. Overall I enjoyed this experience and what you achieved in a week :)
