how do these suggestions sound since i know squat about coding

These are all really weird ideas for games.

I love it

I’d say that ANY of them is a perfectly acceptable foundation for a game in general. The heart-attack grill is probably the only one that automatically lends itself to a weight-gain theme.

Alt-30s stuff is also sometimes called “dieselpunk” and/or “decopunk”, less well known steampunk derivatives that cover roughly the 1920s-50s through retro-futuristic lenses, if you’re trying to describe it to someone or to search for stuff in that genre.
