Fan art, rules or requirements?

[dibs]

Hi guys. Not sure how to contact the developer of Sakyu (is it GoRepeat?) but I wanted to do a piece in my 3d program for fun. I use Blender as a side hobby, not very good but wondered if I could get permissions to recreate some images from the first game and share them as fan art, (also credit to the creator of the game of course) Looking for a small project to do is all.

Thanks.
