I have a quick question: will there also be Macro / Micro content with extreme size differences, and also with age differences ?
Great question! While there's no explicit macro/micro content, probably the closest we'll get to that is interacting with Borovast the dragon (he's a big boi) when you go hiking. As for age differences, yes, there will be interactions with characters who are significantly older than you (as the main character).
The dragon was definitely a highlight already, I'm excited to see where the story goes from here, he's an adorable dragon and the other one is fine too because I just think it's a shame that there are generally very few macro themes in a visual novel.
The daddy crocodile has been an interesting experience so far and, above all, he is a pretty big boy~
