I think this one is really good!
As the game progresses, two 'sides' to the atmosphere definitely do emerge, with the dreams being more pleasant and friendly in a way than the waking world. Seeing as the title is "Sweet Dreams" I assume that's intentional though? So it didn't strike me as an issue.
The gameplay is serviceable, and the idea to have certain food truck spots give different benefits is a neat one. It's not something I'm inclined to revisit though, so I'm glad that the endings are largely on a spectrum of how well the player performed rather than being more equal or esoteric. The thought of replaying this game several times to go for distinct but equal endings is a little dire, it's too monotonous for that. I haven't experienced any freezes myself - just got manic pixie, player-stuffing & true ends - but if I had I'm sure it'd be a slog to deal with. Those issues are more or less inevitable in a game jam, but the boredom in that instance stems from gameplay design rather than technical issues, at least in my view.
That said, the BedBug chases (when they aren't trivialized by her weight~) did instill a fair bit of tension when I came close to her. I think it does a legitimately good job on that front, it feels like stakes are high whether you get hit by BedBug or just the nymphs. Player health seems well balanced, basically.
Outside of BedBug, I'm not sure this game's fats did much for me. It's mostly just getting a brief look at someone fat, which is pleasant but not really flustering or anything on its own. It's very well done with BedBug though, she has a great design and her weight gain is lovely~! (although the ending is a crime as far as I'm concerned, she should stay fat!!!)
I like the unique setting/atmosphere of the game overall c: It felt rather fresh to me, and interfaces with the gameplay and narrative well. That the different tile types - as well as the dreams in their entirety - are based off of the protagonist's past is a nice touch, gives them some grounding and emotional weight. Their existence/placement in the dreams is fully justified by it. It's slick.
The theme's presence seems a tad weak: the player character travels to a new place as part of the game's premise, and then I guess travels about the town/city/whatever in their food truck. Arguably they travel to & in the dreams, but... that feels like a stretch. Personally I don't really care how much it adheres to the theme? >w> But seeing as that's a metric by which entries are judged, it's maybe worth mentioning.
Anyway yeah I liked this a lot!
