It REALLY had be rack my brain around for a while, as I double checked everyone's alibis and recognized the chicken as a red herring. It came down between the friend and the maid, since nobody verified where the friend was at the time and the maid claimed they were in the bedroom, but the bed isn't made, but the friend did verify that the maid was in the bedroom. I knew that there was something suspicious about the cigars, but didn't realize that they were the murder weapon, and that some kind of potion must've been used for the poisoning. Also recognized that it couldn't have been the gardener, because why would a gardener need to steal a book on plants? And it couldn't have been the chef, because if it was, why wouldn't he use his own potion desk? And the maid was the only one in the bedroom at the time, as verified by the friend. So, by process of elimination, yes, the maid.
What I'm saying is, it's AMAZING that you were able to cram so much thought into a Game Jam game!!!
