I’ve had several stabs at creating a weight-gain/stuffing based video game (or sim or whatever), generally when some tool or another caught my fancy. I thought at at least someone would get a kick out of them, so here are the three most successful.
Chub Clicker (play link) is a sim-type game made using the old version of Orteil’s (of Cookie Clicker fame) Idle Game Maker. It’s got a real-time component to it, which I don’t really like, and on the whole it’s a bit half-baked. Also, the layout kinda sucks.
Munch (play link) is a simple puzzle game made in puzzlescript. Your goal is to eat all the fast food in the level, but if you’re too hasty you’ll get too fat to fit into the tunnels. Relatively complete concept, but very few levels and terrible graphics.

(Note: in order to run the game, simply open index.html. Also, for some reason you need to click the restart button in order for the links to show up as buttons.)
Also, bonus: a physics thing (18.6 KB) which I wrote in js using D3, using some of munimunikinoko’s art as a base. You can click and drag, although the effect is very subtle (to prevent it from from being horrifying).
