It's Super Metroid, but on its side.
Play the game with the ground tilted vertically.
Samus and the enemies remain upright and the controls are the same, but the game world itself is rotated 90 degrees clockwise.
In short, everything that used to be ground is now a wall.
"Super Metroid: Lost World" has a new planet, new enemies, huge areas… A must know wall jump and a mid-air morph. It's a game for all players with a mid level difficulty.
Yoshi's Island: Pacifier Edition is a simple ROM hack/mod that mutes Baby Mario's crying and the countdown sound when Yoshi is hit, a feature that could be considered as annoying in the game.
Picking up directly from where the romhack "Super Mario Infinity" left off, Mario and Luigi have discovered an artifact called the Cursed Gem that contains a timed explosive supposedly able to destroy the world, and the only way to stop it is to enter the Gem itself.

Could all of the answers be at hand? Only time will tell (literally) if our heroes can stop the time bomb, or if their planet is doomed to an explosive death...

However, an optional “Double Heart Damage” patch is included for those looking for a greater challenge.
