I like how the game played with my expectations! The red paint on Alle's apron especially made for good foreshadowing/misdirection.
I did find the final parts a bit goofy in how swiftly they seem to take a dark turn, especially one of the final zingers of dialogue. I think it's because Rutile is such an unassuming character. If someone accuses her of being something terrible, my gut reaction is to say "no, she's just a nervous maid." I did enjoy the final narrative payoff, however, and the build up was fun to keep up with!
The pixel art for the tileset and portraits are striking, but the seemingly resized character sprites did irk me as someone who regularly does pixel art. Upon seeing them, I had the strong urge to open aseprite and clean them up. However, those were the only real weak link in the presentation.
It was fun, morbid, and surprisingly cute story to play through!
