I'm using Godot. Here's an example of something (voxel engine) that's already using your textures.

Hey, voxels with textures - that's really cool. Though, you don't have sky textures. Maybe that is something I need to make. And, yeah, tree bark isn't right, cause that isn't tree bark, but just wooden logs. That one I'm definitely going to make.
Will there be a public demo at some point? I would play.
