I gave this a quick play and I've noticed a few issues. First, especially in regards to character creation, capitalization shouldn't matter, especially with things like "both" vs "Both". Second, I found the tutorial a bit frustrating in parts. When Kattie asks you to brew the potion, nothing indicates that you need to give it to her. A simple change in the text string could easily fix this. Also, there should be no reason that you have to 'touch kattie's breasts' multiple times in a row, with no variation in the responses. In a text adventure, that's usually an indication that you aren't accomplishing anything.
I would definitely recommend giving 'The craft of adventure' by Graham Nelson a quick readthrough if you're planning on continuing this.
