Game Name

This name is combined with 2 parts: Duo and Deus. Duo in musical term refers to ‘duet’, means two people playing a piece of music together. Deus means ‘god’ in Latin. By combining two words together, DuoDeus means two gods that are creating music realated things.


DuoDeus is a 2D Local Multiplayer game in which two players (as two deities) cooperate to create a universe by connecting dots, collecting collectables and generating universal things such as whales, planets, explosions and clouds
Player 1 will be connecting stars in the sky in order to create a platform for player 2 to walk and jump on with;
Player 2 will be using the platform that player 1 created to walk, jump and collect the collectables.
Each star contains a pitch on C major scale, and by connecting them a music sequence will be generated;
Each collectable has an unique sound layer, and by collecting them the music sequence will be adding those sounds in, in order to create a unique piece of music by the end of the game.
Whilst collectables are been collected, some feedbacks will generate along with colour shifting in the background.

The game concept is inspired by Taoism’s cosmology: Tao gives birth to One, One gives birth to Two, Two gives birth to Three, Three gives birth to all universal things. In DuoDeus, the entire playthrough is the process of creating universe from ‘one’ (star) to ‘two’ (player 1 and player 2) to ‘three’ (sounds, feedbacks, colours), and finally to ‘all universal things’ (universe)
By the end of the game, players will see the ending diagram, which records players’ journey through music, feedbacks and colours.

Essential Experience

To enjoy fun experience of creating music and painting with friends and families.

Unique Selling Point

DuoDeus introduces a new way of creating music and painting. It allows people from zero music background to music experts to enjoy the process of creation together. By the end of the game, both players will recieve a piece of unique interactive art that contains sounds, shapes and colours, that records players’ journey from the start to the end.
At last, the world responses to players’ action, and there will always be a different outcome in each playthrough.

Target Audience

This is the description for ESRB Everyone:
Content is generally suitable for all ages. May contain minimal cartoon, fantasy or mild violence and/or infrequent use of mild language. 
This is description for PEGI 3:
The content of games with a PEGI 3 rating is considered suitable for all age groups. The game should not contain any sounds or pictures that are likely to frighten young children. A very mild form of violence (in a comical context or a childlike setting) is acceptable. No bad language should be heard.
DuoDues suits both descriptions, and game is targeting at people who like creating or having enjoyable moment with friends and family, therefore ESRB Everyone and PEGI 3 is what we are aiming for.

DuoDeus is a game about gathering people together, communicating and creating enjoyable moments with friends and family. Imagine how interesting it will be when parents and children, grandparents and grandchildren, classmates or even colleagues can create a piece of music and an interactive art together in 5 minutes. This is not only a new way of making music and painting, but also a piece of media that brings people together.
The game is designed to be a foundation that supports player communities. This means that the sounds, feedback and colours will be customizable for everyone, therefore anyone can implement anything(contents has to be restricted under the law and ESRB/PEGI rating) into the game, to create something that has never appeared before. The sounds don’t have to be music, but conversations, rains, water flow etc…The feedbacks and colours will be caculated through programme from anylizsing the sound frequencies that players import into the game.
DuoDeus has the potential to become a software that helps people get closer and create experimental arts.
