What a wonderful little story you've told here, and was weirdly resonate with me. I'm a big proponent of not taking anyone or anything for granted, even though I often tell myself stuff that makes my days a lot worse. I'm constantly annoyed by my coworkers and cashiers, and I find myself feeling differently when "staffing shortages" impede my normal life. Very profound message that hit me.
The writing in general was also really well done and was enjoyable from beginning to end. There were some good setups and payoffs. The main character's arc was well realized. I was genuinely intrigued to see what was going to happen.
The 2D art, while there isn't much of it, is very striking to look at. I'm a sucker for pencil drawings to begin with, and the minimalist, sketchy contrasting with the high-res speech bubble was a great choice. I only wish there were more "scenes."
My only complaint -- and this is minor -- is that there's not much "game" here. I know it's a visual novel and story comes first and foremost, but the only interaction can be done within the opening seconds of the game, and there it's nothing but advancing text, to the point where I felt like I was reading a short story that wouldn't advance until I click a button. I appreciated getting the protagonist's view on certain objects in his room -- it added to his character -- and I would've liked to explore the other areas in the same way. Perhaps update what he says based on his deteriorating optimism.
Fantastic job.
