Ninja Fight, BoojaBaunga in Action

Watch the fluid combo system, wall-runs, and local multiplayer brawling

The Challenge

BoojaBaunga needed a slick 2D ninja brawler that felt immediately satisfying to pick up yet had enough depth to reward mastery. The game required fluid movement, a tight combo system, expressive hand-crafted stages, and rock-solid local multiplayer for two players on the same machine.

Development Process

Key Challenges

Designing a combo system that feels responsive at 60 FPS with minimal input lag, while supporting cancels, counters, and wall-run transitions mid-string

Building a local multiplayer split-input system that handles simultaneous keypress collisions cleanly without ghosting or missed inputs on standard keyboards

Architecture & Design

Built in Unity with a custom 2D combat engine driving frame-data, hitboxes, and hurt-boxes via scriptable object data assets. Movement uses a state machine controller separating grounded, airborne, wall-run, and knockback states. Local multiplayer maps two independent input profiles to the same runtime session.

Improvements & Impact

Ninja Fight, BoojaBaunga delivers exactly the kind of snappy, expressive brawler experience BoojaBaunga envisioned. The frame-data system gives competitive players meaningful depth, while the approachable controls let casual players jump in immediately. The ink-brush art style sets it apart visually from typical 2D fighters, creating a strong brand identity. The project is in active development with online multiplayer and a story mode planned for the next milestone.
