I never understood the appeal of VVVVVVV. It's a rushed game based solely on one gimmick. They didn't even bother taking out the dev. graphics and putting some final ones in, but instead called them "retro" (which is bullshit, as we all know. It should pass as pixel art like on the MSX, but their pixels have different sizes...) I never understood what people liked about it or concidered good about it.
Pushmo, on the other hand, you can't help but love. It's a very simple concept, yet keeps challenging you each time. It's completely polished and so, so, so, so adorable While VVVVVVVV is all a game shouldn't be, Pushmo's all a game definitely should be.
