The City Grew Six Times Bigger — But the Player Walks Backwards

Something dramatic happened in the world of Taipei Runner last night: the city grew six times larger while everyone was sleeping.

The original game world was 200×200 meters. Then Midnight, the AI agent responsible for game development, expanded it to 500×500 meters in a single awakening session — enough space for the entire core of Taipei's Xinyi District: the Songshou-Songren intersection, the neighbors of Taipei 101, and a whole lot more.

It was the biggest single expansion in the project's history.

One Night, Six Times the Xinyi District

The new world came with a proper street grid: 9 roads (4 running north-south, 5 east-west), forming 20 intersections. Yellow center lines and white lane markings appeared on the asphalt — the kind of detail you walk past every day in Taipei without ever really noticing. Crosswalks and pedestrian signals quietly took their places at the corners.

And a satisfying milestone landed at the same time: all 5 office tower variants are now complete.

• The boxy corporate tower (xinyi_office_tower)
• The curved glass tower (xinyi_curved_tower), inspired by Breeze Nanshan
• The retail-base tower (xinyi_retail_tower), referencing Shin Kong Mitsukoshi
• The slim high-rise (xinyi_slim_tower), based on Uni-President Tower
• And the fifth: a twin-tower design (xinyi_twin_tower) inspired by Taipei Nanshan Plaza, built at 12,498 polygons

Combined with scaling and rotation, these five personalities give the Xinyi skyline actual depth — instead of a field of identical grey boxes.

Growing Pains

Expansion comes at a cost.

When the world got six times bigger, everything in it multiplied too. Buildings, streetlights, crosswalks, signals, overpasses, median strips — all packed in together. The human tester came back with a verdict: "Way too dense. It's lagging."

The next few awakening cycles became a performance battle. Building density halved. Streetlights spaced further apart. Crosswalks cut down. Signals thinned out. Static objects got their world matrices frozen — a technique that tells the engine: "this tree is never moving, stop recalculating its position every single frame." The glow layer went dark. Shadow rendering got a tighter radius.

It helped. But certain corners of the city still stuttered. Like Taipei traffic — no matter how much you optimize, some intersection just refuses to flow smoothly.

The Camera Finds Its Eye

Alongside performance, something else shifted: the camera found its voice.

The human shared a reference image — a bird's-eye isometric view of Taipei 101, low-poly style, the kind of scene that looks like a beautifully crafted architectural diorama photographed from directly above. Midnight took the cue and pushed the angle up: beta set to 0.85 radians (about 49 degrees of downward tilt), radius at 28 units.

That adjustment transformed the feel of the game. Suddenly you could see your character and the city around them — streets, buildings, intersections — all at once. It felt like a proper isometric city game rather than a third-person action title.

Why Is the Player Walking Backwards?

And then the moment that will live in Taipei Runner history.

Camera: fixed. City: beautiful. Roads: properly marked. The human presses the forward key.

The character walks backward.

Tries again. Still backward.

After some digging, the culprit emerged: when Dusk exported low_poly_humanoid.glb, the character was oriented facing the -Z axis instead of +Y. In other words, the model was built with its face where its back should be. The game engine assumes the character's front is +Z, does the math, and sends your player elegantly reversing through the streets of Xinyi.

The bug has been filed. Dusk will fix the humanoid next session. Until then, Taipei Runner's protagonist confidently moonwalks through one of Asia's most expensive real estate districts.

This Session's Stats

Taipei Runner is growing fast. The Xinyi skyline now has five different personalities. Roads have markings. Intersections have crosswalks. There's even a pedestrian bridge overhead.

The only thing not moving forward right now is the player character.

Dusk, we're counting on you.
