Dragon Slayer's foes have better coloring and look more polished, but they also look too similar to one another and more generic than those in Cosmic Fantasy.
Adding PCE console specific layer on top of that, makes for an interesting challenge (no, not a reference to Ys II).
I like Dragon Slayers baddies better than Cosmic Fantasy 2's. The bastards might actually look a little simpler/less detailed than CF2, but they are better done IMO.And at least DS's baddies know how to miss once in a while when they attack!! lol
