Jesus christ this game is unplayable! The physics are terrible and they literally freaking reuse levels! And the enemies are just stupid random bs that just kill you everytime! You literally have to be lucky to beat this game since you can just happen to die if an enemy just happens to be there!! I literally can't get past the 8th world because I keep dying to some rng bs, and this is on the allstars version with has a save feature!! The game developers also were generous enough NOT to put any mushrooms or powerups in this stupid world, meaning that if you get hit, you die immediately!! So unless you start the entire freaking game over, you have to stay small the entire time!! Imagine playing this crappy game on a legit nes and having to start the ENTIRE game over because of how random this stupid game is!
