Solid game! Love the vibes, very uncomfy <3 great sense of progression, and i appreciate the prioritization of active play while still allowing semi-passive play.
A couple of notes:
-The font is a bit hard to read, especially when trying to catch whether an upgrade costs 5 or 6 of something; if you end up expanding this, please consider offering alternate fonts. They really sell the brutal tone, don't get me wrong, but readability comes first in my book (the tally/symbol counting at lower amounts are cool though, as are the symbols regarding what upgrades provide-- though you may want to consider a mouseover/explainer for broader acceptance).
-I'm not certain, but it seems there might be an upper bound on the feed speed based on splatter animations/bite sounds; i *could* be imagining it, of course, but it feels like after a few reductions it just stays the same.
-I really like the way you implemented random events/milestones; they really drastically affect the speed of each run. I'd love to know when one is coming down the pipeline, even if it was obfuscated with, say, a weird blob of viscera or something.
-You fit a lot of visuals and information into a static screen, and did it well! The steaks have a propensity for flying off, the rebirth symbols/cracks are a bit too repetitive for my tastes, and the upgradability of passives is a little hard to read when they're almost full, but i'd take all that any day in comparison to having to flip between menus- especially considering how frequently i'm feeding. Sincerely, well done!
Absolutely a great game, jam or no jam. Hope to see more horrible and unsettling updates!
