Jumping Shell Game

Jumping Shell is a clever puzzle-platformer where your character's biggest asset is the shell they carry on their back. Designed by puzzle veteran Robert Alvarez, the game is built around a brilliant mechanic: jumping in and out of your shell to solve spatial puzzles. Sometimes you need the shell to press down a heavy switch, and times you have to leave it behind to squeeze into tight spaces or reach a higher ledge.

Every level is a self-contained room filled with spikes, moving platforms, and locked doors. The challenge lies in figuring out the exact sequence of movements—when to nest inside your layers, and when to shed them. It starts as a simple platformer but quickly evolves into a real brain-teaser that requires both logical planning and platforming precision.

Controls

• A / D or Left / Right Arrows: Move horizontally
• W or Up Arrow: Jump (or hop out of your shell)
• R: Restart the level

Tips

• Leave it as a stepping stone: You can jump out of your shell mid-air to get extra height, effectively using it as a platform.
• Watch your layers: In later levels, you might have multiple shells. Remember the order you leave them in, as you will often need to retrieve them to progress.
• Reset quickly: If you drop your shell down a pit or get stuck, just press R immediately to try a different approach.
