I created a post about your game in my Game Retrospect: https://jmcineo.com/2018/06/24/jmcs-game-retrospect-1/I noticed in your discription that you havent added the anger system! I am looking forward to figuring out how to make him happier!

The anger system is already in the game. The angrier he is, the faster he gets and the glitchier his animations are.
Also, it is impossible to get a rating above F. It is a reference to the idea that the game is a glitchy alpha, in which the game assumes that you interrupted a peaceful dinner by barging into rooms you aren't supposed to be in, and throwing pots at him.
