this is an amazing game to make for just a game jam! i think if you wanted you could make this into a game on steam or something. the mechanics are interesting and make you actually think! the ui is quite good, the gears are quite fun to deal with,
i really don't have much criticism! it's quite a clean and polished game.
the only thing i can think of is maybe putting the mechanic being introduced in each level in part of the ui, unless i didn't see it i struggled with it.
a tutorial could also be good, but a lot of it is intuitive.
apologies i can't think of more criticism! i normally try to be quite critical because it helps a lot, but with this i actually can't because it's too good! overall love it! i hope juniper plays it, this game deserves attention.
