This game is the inventor of artificial difficulty in platforming games. Bad level designs, reverse warp zones, poison mushrooms, and killer springs make you fully aware this game loves to play tricks. The hardcore Nintendo enthusiast, or middle schoolers that found out the US release of SMB2, love to defend this game and hail it as "a Nintendo Hard classic," but being one of those former middle school defenders, I can tell you that's just them trying to be different.

This game is difficult, and not the good kind. Fans of trickery will love this.

There are a certain small percentage of people that will argue that this ISN'T one of the worst, or the worst, video game of all-time. But let's look at this list of points about the game that say otherwise:

Titus literally never completed it, so the finished product isn't finished, leading to glitches and poor hit detection on the lifting levels
The flight control is so sensitive it's hard to steer Supes through the loops, and there is NO way to adjust this unless you have an emulator that lets you adjust deadzone, and even then, the flight gameplay is just unenjoyable
The later action stages are just plain boring and a chore to get through
Failing one of the action/lifting segments or even completing one will often lead you to another maze. Darned if you do, darned if you don't!
*Good luck even trying to advance because the maze stages are impossible to complete due to said sensitive flight controls, and you can't afford to miss even one ring.

In conclusion, objectively speaking, yes, this is ABSOLUTELY one of the worst games of all-time.
