Long chain of replies aside, I think this is really cool, and being able to play and watch cutscenes would really bring out the dramatic moments (saving Twi would feel really involved, I'd love the suspense there) and add to the little hints at the growing friendships between the boys. I like your design for character selection screen especially. I only wish I could help you build this game, since my own stories are going nowhere on Wattpad...
Anywho, it would definitely be exciting! Would it be designed sort of like a virtual novel, or would it be more like the loz games already existing? And are there going to be sprites, or will you build 3D characters? So many questions I'm asking... I'm sorry for being such a gamergirl
