This is a great game and all, but there's just one overarching flaw: the map. It deletes portions you've explored in a seemingly arbitrary way. I beat the final boss early, and when I hit continue, I was back at the nearest save spot with the rest of that corner of the map completely black. I refreshed the page and checked the map; the area is there but there are black boxes about half a screen wide dotted all over the place. It doesn't seem to matter how many enemies you've killed there or how shortly after you save---you're bound to reexplore something out of doubt.
