This was awesome. The graphics, menu effects, square resolution, and game-boy style gave it a cool effect, and the splatter and area reveals with dithering were really nice. And it just wouldn't have felt right without the slight mockery from the signs.
One minor thing that may be my imagination, I only remember hitting one secret on my first play, (afaik the first) but I went there twice and the end screen said I hit 2/3. I very well might have hit two, I wanted to mention it just in case it could have tallied twice.
