well, that was pretty good, as always
i like it, but i do have a rather major complaint: NAAIJ'S LEVELS ARE ANNOYING. VERY ANNOYING, IN FACT. CAPS LOCK LEVEL ANNOYING! anyhow, yeah. the black hole or whatever they are mazes in those levels annoyed the crap out of me.
however, i really liked the whole "here's a long dead race and here's how they died" feel to it. very Lovecraftian, which i like. i also like how it's never directly stated how the planet was destroyed, or what destroyed it. obviously those black hole things, but it's still never exactly stated what they are.
so overall, it's more of a story than a game, but i still like it.
