Glad you like it!
I replaced all the images because they weren't very good to begin with. I liked the Hilichurls, but I decided to give them a complete makeover and give them masks similar to their canon counterparts.
I wanted to include more of the story in the update, but decided against it since it would still end with no real gameplay. I'll wait until v0.5, when I'll finally be able to introduce quests and combat. In short, it will be an actual game instead of just a visual novel.
The next version should be ready by mid-January. It's almost finished, but there's still a bit more to do.
