So creative. The mechanic was actually implemented in a useful way that added to the game. Something that might have thrown some people off is the blurry thumbnail. To fix this problem, I'd recommend scaling the pixel art up 4-8x in an app before exporting as an image. Due to how browsers treat scaling pixels, they usually induce quite a bit of blur, which can be quite damaging for smaller images, whereas apps designed specifically for pixel art don't have that problem.
