There’s only so much you can do with a tileset.
That, I think, is the primary flaw with Cmdr Dats’s Rock Haven stage. It’s a quality level, after all, with some decently well-placed ammo and some good mechanics. While the layout wasn’t the greatest in the world, it certainly wasn’t the worst.
Okay, so the music probably wasn’t the best song, either. But it was better than, say, a disco song (which would’ve been ill-suited for Rock Haven, in my opinion).
The biggest drawback here is a lack of options with the tileset. There frankly isn’t that much there, so JCSers have to get creative.
That’s not easy.
Nevertheless, Rock Haven is still a decent enough level, and is probably worth a download.
