What a surprise!
I was thinking this would feature Marichu (he's better than Sonichu at least) but it did not. From the start, it was still very fun especially with the Koopa cursor icon. I originally thought this was just going to be something short and dumb as it seemed to stop after Mario got his mushroom. You did a great job building up to a tension to an awesome climatic fight! Pointers always make the hardest enemies, particularly with all the guys coming out everywhere. It was a great tribute to the original level in the Super Mario Bros. game and all around great tribute to Mario.
