🥚 Recursive Mechanics and Resource Management

Jumping Shell introduces a unique twist to the puzzle-platformer genre: the Nesting Mechanic. The protagonist is a cube inside a cube inside a cube. To perform a double jump, the player must "shed" an outer layer. This ejects the larger shell downward (propelling the player up) and reducing the character's size. This is a resource management mechanic: your "Armor" is also your "Ammo" for mobility.

The puzzles rely on this size/mobility trade-off. A small gap requires shedding a shell to fit. A high wall requires shedding a shell to jump. But once shed, the shell is gone (unless reclaimed). The player must sequence their "sheds" perfectly to navigate the topology.

🧠 Logic Gates and Spatial Planning

Solving the rooms requires:

Reverse Engineering: The player often has to work backward from the exit. "I need to be small to fit the exit, so I must shed my last shell here. To get here, I need to be medium..."
Hitbox Manipulation: Shedding a shell changes your hitbox size instantly. This can be used to squeeze through closing doors or lasers mid-air.

🎮 Mechanics: Shell Interaction

Physics rules:

The Throw: You can throw your shell sideways to hit buttons or break walls. This turns your discarded body into a projectile tool.
Re-Shelling: If you touch a discarded shell, you put it back on. Some puzzles require you to shed a shell to jump up, then drop back down to reclaim it to withstand a laser beam.

🏆 Puzzle Strategy

1. Conservation of Shells

Do not double jump unless absolutely necessary. Often, a puzzle seems impossible because you wasted a shell on a jump that could have been made with a precise single jump.

2. The Shell Stool

You can stand on your discarded shells. Throw a shell into a pit to create a platform, allowing you to cross spikes.

🛡️ Visual Design

Aesthetic:

Minimalist Geometry: The stark colors and clean lines ensure that the player can clearly distinguish between the different shell layers (Red, Blue, Green) and their functional states.
