Heya! We're in the process of updating all the old CGs to the new art style. You've prob noticed that some are in the same art style as the dialogue portrait. The rest will soon be in that style over time.
I'll update the playtime listing, that was made when we first released the game.
Thanks for letting us know about the bug with Klaus! We' ve had a few reports about it and we're looking into it.
Being able to remove the badge isn't a location-based thing in the programming. Right now you can't do it because we'd want to have special dialogue and events happen if you do take the badge off.
Thanks for playing! ❤
