Great game!!! I know I'm not exactly a deciding factor in the matter, but I wouldn't delete Neal if I were you, everyone in the comments won't stop talking about the character dynamic between Jack and Neal!!! Plus, since I can't really relate to Jack he is certainly my favorite character of the pair.
(Although I am interested to see who you replace him with, if anyone.)
I'm sure it'll turn out great either way, thanks for listening (or rather reading).
1. Zeke or Gramham, although all of them have really cool characterI designs, although poor Ine, no one seems to like him.
2. Really any scenes that show 'our' world views.
3. Yes, I would, although I would enjoy more choices.
4. (Just some random notes and praise) I love how you never really specified 'our' gender, although I'm pretty sure I'm the only guy here. Also, I love the personality you gave Gramham, it's really hard to write in egotistical characters without making everyone dislike the character. Although I do despise you for not making math red.
