I felt a strong urge to experiment with this game. Choices don't disappear once clicked and sometimes even have new text, making me want to try clicking many times. Because the run time is short, I also wanted to go back and look for other endings once I'd finished the first time. Additionally, there wasn't much context or characterization beyond "it's morning, you're in a bedroom, and you dislike your own reflection," so it was easy to detach myself from the character and try options I never would in real life.
The first ending I reached was where I break the mirror and wake up bloodied, but it was easy to find the other endings after that. I did find myself confused in some of the repetition, which was probably my fault because I kept repeating the same options... In particular there was a point where, after exhausting the "You can't stay here, seeing this" responses to your reflection, I made some other choices and thought the story would progress, but it returned me to the same place I was earlier and let me choose "You can't stay here, seeing this" again, and then described the assault of the glass even though I was no longer attacking it.
My favorite parts were the endings, and I liked all three that I found. Most of the experience felt vague and metaphorical, so the moment of clarity when I understood how my actions had consequences was very satisfying.
