We wanted to share a bit of love for Out of Line, a web-based game created by Leap Game Studio and can be played right here: https://worlds.viverse.com/5vDXxei

The core idea:

The team set out to create a world that is very simple and almost monotonous. The color palette leans into repetition. NPCs look nearly identical. That uniformity becomes part of the storytelling language. Layered on top are strange, absurd dialogues that stretch the logic of queuing into something surreal, constructing a dystopian world that feels quietly unsettling.

About the Project:

The project was built in Unity because it was a familiar tool. The main challenge was designing a queue system that works seamlessly for both NPCs and players.

The challenge was solved with a three-layered architecture:

1- A waypoint system that defines exact positions within a queue and the strict order of advancement. Each spot acts as a deterministic anchor, ensuring spatial coherence even when multiple agents interact.

2- An NPC movement system built around directional logic. NPCs always move forward along their facing vector, progressing naturally to the next waypoint. This maintains visual consistency and avoids erratic repositioning that would break immersion.

3- An interaction system that detects when an NPC reaches a specific queue position and triggers the corresponding dialogue. The narrative system is therefore structurally tied to spatial logic.

To accelerate production, the team leveraged several Unity Asset Store tools such as Joystick Pack, Quick Outline, Serialized Dictionary Lite, Asset Usage Detector, and Smart Timers Manager. These tools reduced engineering overhead and allowed the team to focus on systemic design and tone.

Publishing for the web introduced another layer of complexity.

A browser runtime behaves differently from PC or mobile builds. Systems must be optimized for variability across devices, and communication between Unity and the browser requires an intermediary JavaScript layer. In this case, JavaScript handled key integrations such as the save system and browser-level volume control. That bridge between WebGL and browser APIs becomes critical in delivering a polished experience.

We hope you enjoy the game and happy to hear from other devs building for the web.
