Speechless! Literally speechless over how good this demo is! And it's very promising too
First of all, we are already given a variety of choices on how close we allow Ren to be, and I love it. Second, the art style is gorgeous and so well-made! Characters already all look quite unique. Third, I like the small details that you did. Like how different characters can say different thing, depending on what we wear (like when Ren is taken aback by MC wearing alternative style).
And of course Ren! Ren is just great. I am soooo interested to see different routes with him! I can't wait to see his reaction, once he realizes he got intimate with MC the next day :D Overall, this is a very good beginning, and I am just burning up with wait :P
