Just wanted to start off by saying I'm a big fan of this game so far!!! Huge potential, can't wait to see it grow! There's almost no blueberry games out there and this one is an absolute GEM.
I have three small suggestions:
Sounds - perhaps some sounds could help make the game feel more alive? Maybe things like: Bite sound (crunchy w/ MRE and ration, juicy with produce?) for eating, gulping for drinking milk/female bandit, light coughs for contaminated area, air pump for male bandit, gas hiss for balloon trap, rain for the rain event, pop sound on death, etc. Possibly even bloating sounds when very high fill? Just could help :)
Immobility - I do like popping, but I almost wish I could see my character get spherical and helpless as an ending. Maybe a toggle for popping/immobile deaths? It could be like a still render of our character huge and helpless with some text like "Doomed: Immobile" or "Doomed: Berrified" for high infection deaths. Might be hard since there's 4 characters but I was inspired by that really good video you made a couple months ago. To add to this, you could even include the male/female bandit in the render if they were the one to defeat us, but again this might be too much work to do which is completely understandable.
More fill meter helplessness: I really like how the game does acknowledge how full you get sometimes, like how you bump into things (like in the bunker). Maybe more interactions with this? Like if you're very high fill, you may be more likely to fail a run from the rain, or shake off an opponent to stand up. Perhaps some flavour text like "You tried to stand up, but your swollen stomach was too heavy" or "You tried to punch away the bandit, but your bloated arms were too full to move". Just adds to greatly to the helplessness and it's more immersive :)
Once again, great job with this game!! Keep up the good work!
