it's cool, but i have a suggestion. when the characters have went through all their dialogue, it would be great if, instead of looping the whole thing they said, if instead they just repeated their last line. that there's nothing worse n games than having to sit and skip through a bunch of dialogue you've already read. that and as the dialogue is appearing on screen, it would be cool if whhen you push Z as its appearing, it makes it all just appear in case you are a fast reader and dont want to wait for the sentence to scroll.
apart from that, for something made in three days, it was pretty interesting. i don't know if there are any other endings or paths, but it would be cool to see the door lead to more characters and places, maybe have more choices that ipact the endings you get. its a simple yet great concept. great job.
