Oh, I see the demo was already released on Steam in June 2024 (with Kickstarter, although for some reason I can’t see much info on the funding anymore), so this must be the latest demo and also a way to promote the game on different platforms and prepare the itch page before the actual release. Wishlisted and eager to try the demo in the meantime!
By the way, I notice a duplicate link to Steam page in the metadata.
