Ego is an experimental audio game built with Unity where you play musical notes on your keyboard. Tom and Jenna are having a tense conversation. Play the right notes to steer the conversation. Mobile version not supported hehe..
Download the builds folder and you can play Ego.exe
You can also go to the development branch where you can find the Unity project.
Contains a unique but simple branching dialogue system. I believe this system is expandable to include subtitling. As the picture below, you should have designed a structure of dialogues and place them in the appropriate place. Every dialogue line is a number in a conversation.
Let me know what you think!
