The Ink

📺 Demonstration

This is an iPad app that needs to use Apple Pencil. Therefore, it is recommended to use an actual device, not a simulator.

This game pretends to be a simulation of production, but it actually sends a message about environmental pollution, side effects of non-environmental production.

Players can visually accept this message while directly destroying and restoring nature drawn with PencilKit.

Introduction

The rules of this game are simple and clear.

• To draw new pictures, players have to use inks.
• To get inks, players have to erase already drawn pictures.

According to the above rules, this game will be played as follows.

1. I provide players with a picture of peaceful nature.
2. I give players a goal regarding production, and I ask them to draw a factory for that.
3. Players have to erase the peaceful nature to get inks.
4. Players draw a factory with the inks.
5. Players even have to draw environmental pollution from production to make products.
6. When players achieve that goal, I make them aware of the nature that was sacrificed for it, and I send them a message about actual environmental pollution.
7. I give players opportunity to turn everything back, they erase a factory and pollution, and freely restore nature.

Technical Used

The technical challenges I did are as follows.

• Used MVVM architectural pattern with SwiftUI, and handled the interaction between modules with Combine.
• Converted data of PencilKit into images in real time, and calculated the accuracy of the tracing.
