The mechanic origin

The idea came from a billiard session — what if one of the balls on the table could actively chase the cue ball? I prototyped that chasing mechanic, tested it solo, and it worked. From there I worked backwards: what character and context would make this mechanic feel natural? An introvert thrown into an open office — an environment that is, by design, their nightmare. Mechanic and narrative found each other.

Enemy design & difficulty

Rather than scaling difficulty by enemy count alone, I tied it to context. The office environment changes: daytime means coworkers, night shifts bring ghosts with different behavior patterns. The Halloween event introduced zombies, werewolves, and vampires — each with a distinct impact on the player character, with level themes shifting accordingly. This kept the core loop fresh without a full redesign.

Physics objects in each level aren’t decoration — players can use them to block, redirect, or push enemies. Every level has at least two ways through. That was a deliberate choice to avoid the game becoming a pure reflex test.

Brand integration model

Instead of running banner ads, I designed a brand embedded content model: company logos appear naturally in the game environment as office signage and location identifiers. I reached out through my personal network and pitched it publicly — Lazada, Heineken, ZaloPay, and several startups responded and came onboard.

For Lazada, I built a custom level — a branded warehouse environment where Lazada-logoed boxes are the obstacles. The brand gets a playable level, the game gets content variety, and both sides get a story worth talking about.

Tools & process

Built with Buildbox — the right trade-off for a solo developer who wants to validate mechanics fast rather than build infrastructure. Multiple iteration rounds before shipping, testing until the physics and pacing felt right across all level types.
