absolutely adored this, love playing through it and trying to see what all endings i could find and tearing myself apart over the dialogue between the two characters.
the last goal i had was to beat the hero after transforming once i got the "one more time" dialogue. but i wasn't able to hit them once in that state over several attempts, so i assume they effectively become invincible at that point, if not incredibly difficult to make contact. it's kind of fitting though; one with enough hope and determination can overcome despair, especially with a goal close in sight. alas, the hero has more of those than i do. ^^;
