I love seeing how much your art style has evolved since you made "When I knew you". It's my favorite thing about artists is watching their style change as time goes by. And the writing of course is amazing like with all your other VN's :D
Yeah I had the same thought! Maybe for an anniversary of when it was first released Konpeito could update the sprites when they aren't making any VN's. Though I would prefer it be a separate version or like toggle able in the settings, so we can have access to the original version.
