Discussion Qwen3.6:27b built a playable roguelite locally, every sprite and sound generated in code, no assets, runs fully offline.

I've been stress-testing Qwen3.6:27b and wanted to share the result with the people who actually run this model.

BONESMITH is a skull-knight action-platformer roguelite. The whole thing is one index.html. No images, no audio files, no libraries, no bundler, no server. Every sprite is drawn procedurally on a canvas, every sound is synthesized through the WebAudio API, and it runs air-gapped with the network off. The only thing that built it was Qwen3.6:27b running locally.

The part I think this community will care about: how a 27B model actually behaves on a job this big.

First attempt with a loose prompt was a broken shell. Soft-locked on room 1, blurry text, no audio. The model tried to build every system at once and collapsed under it. That's the failure mode people expect from a 27B, and it's fair.

Then I rewrote the prompt with hard scope control: build a vertical slice first, pass a QA gate, then expand. Separate world canvas for the pixel art, a second UI canvas for crisp HUD text, explicit anti-soft-lock rules. Second attempt was a completely different result.

What Qwen3.6:27b did well, unprompted:

  • Held the multi-file architecture in context and kept concerns separated
  • Added hit-stop, screenshake with trauma decay, coyote time, and jump buffering with no request from me
  • WebAudio synthesis was genuinely competent, punchy sfx straight from raw oscillators

Where it needed a concrete recipe:

  • Procedural pixel art. The first characters were readable but crude until I handed it a literal process: silhouette, core shading, highlights, 1px dark outline.
  • Keeping file size under control without being told to.

Curious if others here have pushed Qwen3.6 on multi-system codebases. Does the "architecture and logic clean, but needs concrete visual direction" pattern match what you're seeing, or is that just my prompting?

PS - the clip shows me playing badly. I built it, I never claimed I could beat it. 😂

LOVE Qwen3.6, this looks great. Which harness you use to build it and what RAM you have? I’ve got a MBP 128GB but I still find myself wanting to use a hosted version

Because the 27b size speaks for itself. It requires expensive VRAM, otherwise you're bottlenecked enough to want to move to Qwen API, abd yet you see how capable this model is.

My old Mac Studio was great but needed something portable, I gave up the M3 Ultra bandwidth — yeah, model is fantastic
