Guten Tag!
Looks fascinating. I do a series every Friday where I stream new Itch.IO games on Twitch and give impressions. I think I'd love to start with yours, would be super cool to do. Let me know if you want more information. The stream is US-EAST based, so 7:30, which might be late if you're in Germany, but the VOD will be up as soon as it's over.
From what I can see, the screenshots look great. The minimalist style combined with the handdrawn portraits look awesome, and I love the concept of the Shadow World.
Looking forward to it!
