Nihilist, realistic mario for the win.
I like this. This is, this is the way Mario should be. Or should I say, this is the REAL Mario. I like how Mario and the enemies look more realistic, more believable, uglier. The enemies are grungier, more disgusting, at least the mushroom things are, they're grotesque. And the little details, like how when Mario grows but hasn't gotten any firepower, when idle, he periodically scratches his butt while standing there.... but once he gets firepower, he shows off his tiny bicep muscle, to signify that he's strong now. And it ends with the princess being a lie (portal reference, the cake is a lie). She's not just not in another castle, she's a lie, she don't exist, he gets no reward for defeating the boss, and everything he's done, has been pointless, no one cares about your accomplishment and it doesn't matter, and what have you been doing all this time? Running around, stomping on and immolating a bunch of animals, that's all, so congratulations on that. It's somewhat satisfying to get all 99 coins, all the items, kill all the enemies and win it with 0 deaths, but ultimately pointless, you don't get anything extra for it. Nice mine turtles too. Also, even though the music is fairly simple on a short loop, I like it more than the original mario music too. It goes along with it in no sense being a jolly situation. Kind of reminds me of the canabalt music. Grim and setting the mood at pessimistic.
It's a revisit to Mario, to 1985, but of course, when you look back and try to recapture the past, it's not the same. This is why time travel desperately needs to be created already.
