I like the art style. The music is very nice too.
I feel like there could be some simple more clear indication that the purple biscuits are infected or something. I also didn't understand correctly what is the purpose of them because it costs the same to make. Maybe they could be cheaper to incentivize to use them, otherwise I can just make the good ones forever and keep earning revenue, the game seems pretty linear in that regard. The poisining doesn't seem to be that much integrated in the progression of the game. You could probably go bankrupt by only making good biscuits, that way you need to poison some of them.
I don't know if you check the ration between good and poisoned biscuits you give to characters for the suspicion to increase (for example giving 1 posioned biscuit and 1 good biscuit is worse than giving 1 poisoned biscuit and 2 good biscuits), but would be nice to see.
The game could be more polished though. But the on my second day, something happened and now there are always 2 characters rogether and when I sell, I only sell to one and the other leaves without any biscuits. There is also someone already waiting as I bake the biscuits...
