Turn on the radio, listen to a song and take a look around your room. The protagonist talks about their own experiences in this game, thinking through the various ups and downs (but much more of the latter) which life has put them through, including their pet, job hunting, their game dev career and so on.
One thing I liked was the hand drawn art style along with the muted choice of colors. It helped to convey the melancholy mood of the writing. There's also an interesting song playing in the background.
Gameplay consists of going around a house, navigating by arrow keys and interacting with different items on screen. Each item leads to the protagonist talking about their own experiences and memories. I'm not sure if the game has an ending, for as far as I can tell, I could continue exploring the house and interacting with the objects even after (I think) activating everything available in game.
Another difficult question is whether this fits the single choice requirement. I suppose we could treat the entire room exploration segment as a single choice, although that would be a very liberal (but probably still somewhat reasonable) interpretation of the rules. Anyway, I'm not sure where the precise lines are drawn, so I'll leave it as that.
It was an interesting read, especially given that I could also relate to some of the things mentioned in the game. It might not be the best example of a single choice game, but I'd still say it's worth a read.
Note: I played this on my phone. You could play this on your desktop, but the screen dimensions might make things hard.
