Super Mario 2: Ghost Island

Super Mario 2: Ghost Island traps Mario on a dark island packed with graves, monsters, and wandering ghosts. This platform game doesn't ask for a straight run to the exit. Sweep the stage for every star first. Only then does the locked door at the starting point become useful, and that's how you finish the level. Regular enemies go down when Mario lands on their heads. Ghosts don't. If one floats into your path, move past it and keep going.

How to play?

Move through the stage and search the full area for stars. Check platforms, gaps, and dead-end paths before heading back. Jump on monsters to remove them from the way. Don't try the same move on ghosts. They can't be defeated, so dodge them and keep your distance. After collecting all stars, return to the beginning of the level. Enter the door that was locked at the start to clear the stage.
