Shock Lobster

Copyright 2021 Dave VanEe

Shock Lobster is a Game Boy ROM designed to run on the original Game Boy handheld video game system using a flash cartridge. It should also play well on most emulators.

Venture forth on your quest as a lowly lobster imbued with magical powers, determined to inflict lethal damage to whatever stands in your way!

You start out with a handful of skills allowing you to avoid oncoming obstacles and deal damage, but will use the pearls you collect on your way to unlock more skills, upgrades, and items to push your high score higher and higher.

This game is an entry for the Game Boy Competition 2021.

Controls

Loadout Controls

Battle Controls

Items are either usable at the beginning of battle or when defeat is near. The prompt will only be visible for 2 seconds, and can be hidden early by pressing START.

Gameplay Details

Press SELECT on the status screen to show detailed information about each skill, helping you decide how and when to best use the tools at your disposal for maximum output.

The A and B (X and Z) buttons are used to activate skills in combat, with the D-Pad used to select which pair of buttons is active. By default the selected pair will stick to the top pair when the D-Pad is released, but this can be disabled on the status screen. Skills may consume your energy, which is constantly refilling, or generate charges, which are consumed by finishers which scale with the number of charges used.

Several of the skills apply damage-over-time effects to the enemy, time-limited buffs to yourself, or have cooldowns before they can be used again, which are represented by bars on the bottom-left of the game screen.

The game speed and loadout/items used will be summarized on the game over panel, allowing you to compete with your friends to get the highest score using a specific combination of skills and upgrades!

Note: If the game is running from a flash cart without SRAM, skills/upgrades/scores will not be saved between sessions. To help with this, you can hold SELECT as you start up the game to unlock all skills/upgrades.
