== 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.
Loadout Controls:
-----------------
D-Pad: Select item
A: Confirm/unlock/toggle
B: Back
Select: Show/hide details (these are very important, and also included below)
Start: Start game
Battle Controls:
----------------
D-Pad: Select active button pair
A/B: Use the corresponding skill from the current button pair
Start: Pause/Unpause
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!

Changelog:
----------
2021-10-01 (ROM Version: 1):
- Save new highscore/pearls when game is over, instead of when returning to the
status screen, as it feels natural to power off at game over and you'd lose
your progress before
- Change corners of SELECT tiles from color 2 to color 1 (lighter) to match
START tiles
- Add DAS (delayed auto shift) to left/right cursor movement on status screen
- Fix a single frame visual glitch at the end of the bootup logo effect
