Pixelbound: Lost Signal — DeepSeek v4.1 Flash
A complete pixel platformer with touch controls — built through Ezkielyna API for about three cents of usage.
About this project
PIP the courier robot runs, jumps and dashes through Signal Meadow, Circuit Caverns and Glitch Tower to reactivate their signal towers. 17 ES modules, pixel sprites drawn into offscreen canvases, and all audio synthesized at runtime. No external assets and no build step.
Controls: A/D or arrows to move, Space/W/Up to jump, Shift (or K/L) to dash, S/Down to drop, Esc/P to pause, R to restart, M to mute. On touch devices an on-screen pad appears.
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: 424 requests, all successful; 24.6 million input tokens (mostly cache) and 241 thousand output tokens; usage charged at Ezkielyna API prices: $0.033. Four sessions. Its self-test caught a crash when starting a level, and the model fixed it before finishing.
Notes
From the model's REPORT.md (known limitations): three levels only, no boss fight, Sentinel enemies can only be beaten with a dash, secrets are proximity triggers rather than gated rooms, and there is no full-run high-score mode.
Feedback the maker is looking for
This one cost about three cents of API usage. Does it play like it? Tell us what surprised you.
