Not just one of the best Flash games ever made, but one of the Mario fangames with the most care and effort put into. It's clear this game was born out of pure love of Mario games, and it shows most of the time. Of course, as a Flash game, it can get a bit rough in some aspects such as performance or controls, but it's well optimized overall. Even though Super Mario 63 tries to add some quality-of-life features, some more would've been appreciated, such as the ability to continue playing a level after getting any star, but despite that it's still aged like fine wine. I also felt like F.L.U.D.Ds made this game a lot easier, to the point I panicked and choked a lot in some stars where you aren't allowed to use them. May not be the most well-balanced game, but it's a work of art made out of sheer love for a franchise and it must be appreciated for what it is. Legendary game in Flash history. May you rest in peace, it was fun while it lasted.

Unfortunately though, the emulator I replayed this game on gitched on the final battle and softlocked me, so I had to watch the ending on YouTube. Not the creator's fault, though, so I didn't take that into much consideration, despite being a shame that I had to abandon at the very end.
