I doubt that this is really GPL licensed. Normally the source code should be provided with the binary, which is not the case. Apart from that, I could not find an official reference from Blender Studio to this itch page leaving me a bit suspicious whether this is actually an authentic release page.
edit: The license is now MIT and there is a link from the official blog post to this page. Thank you for clearing that up and taking those issues seriously :)
CC4 for the graphical assets
GPLv3 for the programming code
Also see https://itch.io/post/13347732
this only applies to distribution in a physical object (section 6c.1 of the gplv3) but what applies here is (at least how i see it) section 6d which reads as follows:
> Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge.
(this is only an excerpt)
the "equivalent access" is what i think is not given, since we have gratis access to the binary, but not to the source code.
but they promised to clear that up soooo...
cute game btw
Sorry for the confusion. We'll make sure to include the links to the itch store page more consistently in our posts to make it look more legit.
The license of our sources is a bit muddled. We'll try to clear that up asap. The full production repository is CC-BY since it mostly includes the original art assets. The source code (scripts) are licensed as MIT.
All of these assets are available to download through our website but we didn't make the original git repository public (same for any of our other projects).
