This all screens looks really great, but the worst thing for me here is, that A8 still uses textures from A3...
Otherwise, I have to say that levels are great, and someone had done a great job.
Replacing the textures afterwards is no problem.
However that's not the point of the project. I try to bring over the A3 levels to A8 with as much accuracy as possible.
All further improvements like shader party or better textures are then up to the user.
If you want to replace textures, you just need to replace the image files.
