You guys should remove the rose tinted glasses.
Judging from these particular screens the snes version looks extremely flat(some architectural elements aren't easy to decipher) and dark, the 2d android version looks more vibrant, with more depth and closer to a 32 bit game and the new version looks flat because of the lack of shadows and darker tones, if they didn't do such mistakes it would have looked way better.
Judging from these screens the 2d android version is clearly the best one graphically.
That said this new version looks exactly what it is, a cheap looking mobile game, square could have easily improved the graphics on all platforms(vita included).
