Duality
Character Designs - Keith's design really fits his character, it fits well with his warm personality along with his hobbies. And as for Temebris, his design is such an eye-catcher. By that I mean I love his dark themed look, it gives me overall punk vibe. His outfit is completely the opposite from Keith, which is such a great detail to what is currently happening for them.
Plot - Quite short but this is still the demo. This game has a great hook which makes me want more of what's to come, I'm very excited for the next update on this game!
Should you play it? - Yes, of course. This game has a great introduction to the characters and your choice is actually remembered by them! They seem to comment on every choice you've made in the game, which is refreshing to see even if its just some dialogue.
(Spoilers)
Keith - Keith seems like a calm and nice person, he seems to be handling the situation with him and Temebris okay, considering his situation. Keith has a warm personality and design, at first glance you know he looks soft. Seems pretty polite.
Temebris - Well Temebris here doesn't seem to know when the conversation has ended, cause he kind of just goes into your house expecting to talk more. I honestly love his obliviousness to common sense, it makes him seem so much like his own person.
