you right! This SUPER MARIO new version really is broken, the levels "feather challenge" and "green demon cave" are almost imposible. This game has many bugs where the most gasthly bug make computer to freeze and need to force restart not only to close program with error.
I’ve beaten both those levels, albeit with some difficulty, but damn bro, they’re not borderline impossible. Green Demon Cave is neat because you have to plan your route through the level and be smart with your movements, and Feather Challenge requires mastery of the (admittedly slightly janky) feather powerup. As for your software problem, I’ve never had anything like that happen to me. The worst extent was when the game would immediately close after trying to load a level.
