Optional Boss: Koopa the Devastator can be found in a secret area in World 2.

Exaggerated during the True Final Boss fight against him in 9-6, which has four layers of health His final battle in World 8 has two layers of health.

Life Meter: Bowser has a life meter which goes down by you jumping on him.In a Single Bound: The jumping bean is a very rare powerup, but it lets Mario jump really high (and slow) so it's easier for him to land at certain areas.Edible Ammunition: Mario can turn into Potato Mario, who fires out bouncing potatoes that can destroy blocks.The game is also nice enough to give you a checkpoint before fighting the final boss after fighting through a grueling tank level.

However in later builds of the PC version and in the majority of the postgame levels (but not the Human Lab), there's several signs where you can touch to get a checkpoint. Checkpoint Starvation: In earlier versions and the ROM hack version, none of the main levels contained a single checkpoint.In the ROM hack version, you're taken to a smaller simplified section similar to Bowser's base in Super Mario Bros 3, but the music is less bleaker compared to the original. In the former, the map is all fogged up and the music starts bleak and scary until 40 or seconds in, when it ends up sounding more epic (said part plays in the 3rd and 4th levels, showing things are about to get serious). Bleak Level: World 8 (in both the original and ROM hack version) are both noticeably darker than the rest of the main game.The game unfortunately has malware (one of which is the Mario Forever Toolbar, a browser hijacker), but a fan remake using the Super Mario World ROM file was released in 2021, still allowing players to play without any risk. The story is simple: Bowser launches an invasion at the Mushroom Kingdom and kidnaps Princess Peach, and it's up to our hero Mario to rescue her. The game plays similarly to the original Super Mario Bros., alongside a couple of graphical adjustments and secrets here and there. Mario Forever is a Mario fangame that was created by Softendo (Buziol Games until 2009) that was released in 2004 for Windows.
