I played this game with at least three different saves. Once on an older computer before Flash was discontinued, recently on this one, and then again on this computer after due to misclicks I wiped my save trying to import a save. There are a few bugs, but this is otherwise a great game I played many nights. I managed to, knowing about the secret Switch, unlock that on my first Switch Palace by holding off on activating it until I snagged a flight powerup after 1-7. I noticed at one point I was able to somehow re-enter the blue Switch Palace I think. I also triggered a bug by hitting F so close to death, that I returned to the mapo screen with the fire flower form. I at one point managed to just barely touch the goal gate in a sky area in 2-1, and then fall down and hit the regular gate. I also had no choice but to quit the game when my keyboard built into my laptop got stuck on left arrow, preventing me from saving. I should note that I guess I was playing this game when my laptop keyboard failed last night. I can't blame you for that. Anyway even after getting pretty far I never actually beat the game yet. And I remember from on my old laptop the graphics weren't as good before this update. And the Snow Day key was too hard for me to get. Overall, a great free Mario fangame I think I have been playing more lately than any actual official game.
