A short version of the Game Design Document for BattleBalls
OUTLINE
BattleBalls is a short Android and PC game that sees 2 players compete in a pong inspired contest.
Players have to defend their goal whilst trying to score in the opponents. New balls will enter the arena after set times and an extra time multi ball mode at the end of regulation will see a randomised amount of balls all unleashed at once causing complete chaos and leaving the trailing player a chance to comeback right to the very end.
Each character has an energy surge meter, the meter has 3 segments, 1 segment can be used to emit an energy surge or all 3 can be combined to use the player’s special move. Segments can be gained by scoring with the energy surge ball.

ART STYLE
The art style for BattleBalls is inspired by hand painted textures and the simplistic but eye catching style of The Legend Of Zelda: Wind Waker.
The models will be very low in detail to add to the art style as well as help performance on the mobile version
Guide for texture creation:
Cracks and Highlights shades (usually only one or the other but there are some exceptions)
Base colour
Shadow colour
Light colour
Pattern (only if it improves the look of the texture)
Give more detail on important objects
Blur & smudge between different shades
Large areas of shade rather than small detailed areas
Shades can’t be too far apart especially on non important objects otherwise they will be too distracting and keep taking the player’s attention rather than blending into the world.
MUSIC STYLE
The music style will also contain inspiration from older franchises such as Crash Bandicoot & Banjo Kazooie giving the game a pure fun and friendly feel to it. The main menu theme will be a slower song that blends into the background. The in level songs will be more fast paced to fit the chaotic style of the game.
