However, I do have a piece of criticism to offer: if you intend to make more games like this, as in visual novels that involve boss fights, maybe try to not make them luck-based? I know it's multiple choice, but it's why I can't say the final boss is all that fun, because of the limited time combined with having to guess at every screen before the ending -- and getting even one screen wrong sends you back to the beginning of a phase.
Either you figure out the pattern through trial-and-error, and have to memorize the exact choice for the exact screen, or you cheese it by saving whenever you get to another screen and continue to load the game until you get it right. That's how it went for me, anyway.
