Thanks. Yeah, this one's giving me a lot of trouble, mostly with palette but not exclusively. I'll try to work on contrast (which has been noted before as a problem for me), thanks for confirming suspicions. Really I just allocated too few tiles to do too many things. I am curious to know what you identify as tilebugs though (as if it really matters for an example level), and by "the cave background blend[ing] in with the stonar blocks," do you mean the purple bricks or the gray blocks? If the latter I don't see that at all.
