BoxBoi-Unity

Completed Started November 21, 2019 Ended November 23, 2019 0 Views0 Likes

48 hours. One weekend. One game. BoxBoi was my entry into a game jam where the clock was the enemy just as much as the obstacles on screen. I built it in Unity over a single weekend in November 2019 — designing the art, writing the C# scripts, and shipping a playable endless runner from zero.

The concept was simple: a tiny box character, an endless world, and increasingly chaotic hazards — including, somehow, Nicolas Cage's face. That's what happens when you're deep in a jam and creative decisions get made fast. I handled both the visual design and gameplay scripting, which meant constantly context-switching between Photoshop and Visual Studio with no time to second-guess anything.

Game jams are my favourite way to build. The constraints force you to commit, ship, and move on. BoxBoi isn't polished — it's scrappy and weird and exactly what it needed to be. Proof that a complete, playable game can come together in a weekend when you stop overthinking and just make the thing.
