Hey Kenneth,
I understand your concern, but since we are a small indie studio we are trying a lot of things out and this preorder shop is just one way to support us and the game in the end. That doesn't mean we will only release it on Steam or the Nintendo E-Shop and are also looking into other revenues. But if you want to support us before the release, in advance so to speak, this is a possibility.
Also some of the Bundles, like the Lore bundle or the TTRPG bundle which doesn't contain the main game, but a lot of cool DRM-Free digital goodies, which could be worth checking out.
I hope that makes it a bit clearer. Cheers,
Tommy
