I think you managed it perfectly to create an atmosphere in the spirit of your mangaka inspirations. And by that I don't just mean the artwork itself, but also the kind of storytelling. The painting gets more and more important in the game, and I admire your skill to focus on one object so much. I'm looking forward to the full version of that, but even the state of the game right now is pretty great! :) I wrote a little article about it and also created a gameplay video for everyone who is interested - may more people play your game. <3
Best wishes,
Sebastian
