That's...straight-up false. Unless you have some source for this, you're just lying here.

Yes, it's inspired by Minecraft. The screenshots are of voxel-based survival crafter games you can build with their platform. The textures are not Minecraft textures. They are similar in style, sure, but that's not remotely the same thing. You can't copyright a general visual style, nor can you copyright a game genre.

To call this anything but "baseless" would be hilarious.
