Demo Game
I created this game to demonstrate the tool, utilising the API set out the user manual.
I harnessed the sentiment-weighted relationship system to create customers that consider their recent experiences when updating their relationship with player.
The skill system allowed me to apply varying difficulty to the minigame, based on the active skill and the player’s experience level.
The tool seamlessly handled saving of skill and relationship data.
To show off the tool, I also developed a dialogue system to fetch appropriate dialogue based on the context and relationship with the player.
I implemented a live demo window displaying the tool’s variables in real-time, helping users assess integration and functionality.
