Gameplay in Signal Meadow: PIP near spikes and floating platforms with glowing Signal Bits, built by DeepSeek v4 Pro

PIP the courier robot restores signal towers across three levels: Signal Meadow, Circuit Caverns and Glitch Tower. Vanilla HTML5 Canvas and ES modules, no frameworks and no external assets: sprites are drawn in code and every sound is synthesized with the Web Audio API.

Controls: A/D or arrows to move, Space/W/Up to jump (hold for higher), Shift to dash, Esc to pause, R to restart.

Why it was built

Part of Model Arena #02. Same brief as Arena #01, but every request goes through Ezkielyna API, so the usage behind this build is on record.

How it was built

Built entirely through Ezkielyna API. The model worked in a small open-source agent (list, read, write and edit files, a syntax/CSP check, and a headless-browser smoke test) with no shell and no internet. Every line of code and every design decision is the model's own; sessions that ran out of steps were continued from its own files until it called finish.

Verified in the Ezkielyna API gateway logs: 374 requests, all successful; 21.4 million input tokens (mostly cache) and 219 thousand output tokens; usage charged at Ezkielyna API prices: $0.372. Four sessions. Its self-test caught a menu that rendered off-screen, and the model fixed it before finishing.

Notes

From the model's REPORT.md (known limitations): audio starts after the first input (browser policy); collectibles reset on death; moving-platform carrying is approximated per frame; the vertical camera is intentionally gentle; reduced-motion lowers particles and shake but does not remove every effect.
