I remember playing this demo some time ago and by that time I was confused on what was happening and why the plot was this way. But so far, you really sold the dreary and bleak atmosphere. I like how it feels slow and boring at the first part and the pure monotonous progression shows MC's further mental state.
I like the twist at the end especially with the test scenes where we can be able to gather the real role MC has and how it goes against the traditional roles of what MC and the LI have which is very intriguing to see it in a different POV.

I have to say! I had an inkling on what the "roommate" was but I really like how we really see the thriller aspect of yanderes and how their obsession is downright terrifying when not in the lens of their love interest. I also like how you can see the roommate hesitating in the test scenes to take MC's life but in the Bad End in the actual game, you can see that the Roommate didn't even hesitate in answering the questions and a lackluster response. Probably the shock of killing someone faded overnight.
Really hoping we see more lore from the Roommate and seeing MC's mind work overdrive to outsmart the murderous killer. Great work!
