Thank you for the comments. I might have to try seteffect to see what kind of effect (lol) it gives me for lava stuff.
If you wanted to see more of the first image (the old schoolish one) click the forum link under it and download the zip and run new2.nw and there’s a few levels in it. It’s quite an ol’ version. Though it’s the only version now as I lost a lot of quality levels when I had to format my PC a year or so ago.
