Looks good and it seems it will be fun in a couple of updates
MC is The Pagemaster kid and the kid from The Mighty but without an enchanted library or the buff friend support, just imagination and naivety, which is cool, I like that part. The family looks good too, mom is super hot and bouncy, mega thots sisters are hot too and they come in two flavors, gyaru and goth, and step-dad and bro are not that terrible to code lyoko Jeremie
What the other users said about being able to track other characters and reducing the amount of clicks you need to navigate would be a good thing to add, blind exploration is kind of annoying in this type of games specially because there are a lot of areas to visit, which could become a problem
About the ntr, I don't really care as everyone here can read the tags and ask around, and is optional in the most direct sense (don't pick this route and it won't happen), unlike being "optional" in the sense that it does happen but you're not made aware of it, as it is now, I see it as a non issue and I think we should wait to see more, I understand that at some point some routes might take more attention and development that others and the focus will be there, but that's just natural for what the dev wants and this is just a demo, so there's that
Good luck rabbit guy
