One big issue I'm having is the "hidden" words. If it has a response, it should be in the list. (Horubrain, Shop, Cheat (even though it doesn't do anything anymore, it should at least be listed since she responds to it), etc). I'm giving these out because they don't appear in the list either way so it doesn't help anyone right now.
Another thing is the list should be in a better order. Animals should be with animals, feelings should be with feelings, and if something is used often it should be at the top. Yes, the three you use all the time are up there but still in a rather odd order. In order from oldest to newest (except a little tweaked) makes it overwhelming to look through.
That or you can put it from First Word You Found to Latest Word You Found (not my favorite but better than the order it's in now, I think.)
All this to say I am LIVING for this game, and I'm addicted. It's very hard though. Another suggestion I have is for her boredom to give a drink you don't have already first, instead of a random one, and hints should be what you don't have first.
If I'm 174/189 and she's giving me a hint for Life after I've already used it a million times to bring her back, that's just frustrating. At the very least she shouldn't yell at me if I'm like give me a new hint, I heard her hint already. I've given her the drink ten times. She should know I don't need help finding it.
