Hi Mausakrobat28! Thanks for the feedback.
No Steam plans just yet. My goal is to keep the game accessible. The base version of the game will always stay free here on itch.io, so you don't have to worry about payment hurdles or regional blocks in Germany.
That said, I am considering opening a Patreon soon for those who want to support development and get early access to new builds and behind-the-scenes content. But again—the versions on itch.io will remain free to play for everyone.
Stay tuned!
