I'm glad you enjoyed the game, especially the a e s t h e t i c s! There's 4 levels or episodes in total, so you did end up seeing most of the content that's in there right now. (Specifically, there's the one with the car, the one with the D&D game, the one with the school, and the final episode with the two different endings.)
The sitcom theme with the exaggerated characters and cheesy jokes is very big and loud, so it's great to hear that the subtler touches came through. You picked up on a lot of the details. It's true that there's no over-arching plot, since that's not how it works in sitcom land, and the episodes are more connected through characters and themes. The main character's sense of alienation is meant to be a bit of a through-line, for example. The final (4th) episode does sort of wrap things up, though.
The gameplay wasn't the focus, as you've written, but it's admittedly a little weak. That's something I'd need to work on, if I was to develop this into a longer game. I didn't want it to be a pure walking simulator, but perhaps making it more relaxed would've worked better. I'll have to look into that.
Thank you so much for all the feedback, this is really useful!
