What happens when you give a dog a keyboard and a Claude Max subscription? Quasar Saz apparently.

This is a game vibe coded by Momo, a 2 year old cavapoo, and kept on rails with tools developed by her human Caleb.

Quasar Saz is a cosmic musical arcade game about an alien named Zara who fights corrupted sound with a stringed instrument called a saz.

## Downloading the game
If you want the best most playable version, then [grab the version with some human added bug fixes
and usability enhancements](https://github.com/cleak/quasar-saz/releases/tag/v1.1). If you want the exact version Momo made with 0 human intervention,
and don't mind some bugs, then grab [Momo's unmodified game](https://github.com/cleak/quasar-saz/releases/tag/v1.0)

## The Concept

My dog typed on a keyboard. [Claude Code](https://docs.anthropic.com/en/docs/claude-code) read her keystrokes and decided what they meant. Every mashed key, every chaotic string of characters was treated as a cryptic but *intentional* game design directive. The AI was instructed to never dismiss any input as gibberish. Every character had to mean something.

The result is a complete, playable game that no human designed.

## Momo's Design

Momo's initial design for this game was:
```
wsaqq4e3wd232`21sazqa
```

Which of course means:

The game is QUASAR SAZ — you play as ZARA, a quirky rebel alien musician wielding a legendary cosmic saz,
trapped in the Sound Dimension where music IS reality. Strum your saz to fire sound waves, ride amplitude pulses, collect lost melodies
across 4 synesthetic worlds.

| Keys | Meaning |
|------|---------|
| w-s-a | WASD cluster = free movement, wandering, adventure |
| qq | Quick-quick = urgency, double-tap mechanic |
| 4-e-3 | 4 worlds, energy system, 3 abilities |
| w-d | Waves + Dimension = sound dimension setting |
| 2-3-2 | Oscillating rhythm pattern (wave/pulse mechanic) |
| ` | Hidden secrets (the console key = secret areas) |
| 2-1 | 2nd chance revival, 1 hero |
| s-a-z | SAZ - the Turkish cosmic string instrument! |
| q-a | Quasar + Amplitude = cosmic sound waves |

## How It Was Made

The pipeline has three parts:

**1. The Designer (my dog)**
She learned to swipe her paw across the keyboard. The output looks like `skfjhsd#$%` or `mmmmmmqqqqq`.
To her, it's a rewarding activity she loves to do. To the AI (Claude Code), it's a design document.

**2. The Interpreter (a system prompt)**
A carefully crafted prompt tells Claude Code to treat every piece of chaotic input as a meaningful game design instruction. Letter repetition might mean "more of something." Harsh characters might mean "danger." The overall rhythm and texture of the input shapes the creative direction. The AI is told: *"You MUST make use of EVERY letter I give you. No hand waving."*

**3. The Developer (Claude Code + guardrails)**
Claude Code writes all the code, draws all the graphics procedurally, synthesizes all the audio from sine waves, and tests everything. A suite of custom tools ensures the output actually works:

- A DevTools runtime that can screenshot the running game, simulate input, and validate assets
- A full test suite (48+ unit tests) that must pass before any change ships
- Shader and scene linters that catch broken references
- Input sequence files that automate gameplay verification

The dog provides creative direction. The AI provides execution. The guardrails ensure nothing (or at least not much) breaks.

## The Game That Emerged

Through several rounds of dog-typing, a game materialized:

**Quasar Saz** is a wave-based arcade shooter set in a cosmic sound dimension. You play as Zara, a teal alien rebel musician, fighting through 6 waves of corrupted sound enemies with an evolving musical weapon (a saz). The game culminates in a boss fight against the Dissonance King.

Everything is procedurally generated. There are no sprite sheets, no audio files, no imported art assets. Every character is drawn with code. Every sound is synthesized from sine waves and noise. The background is a GPU shader simulating a living nebula with aurora waves and twinkling stars.

Key features that emerged from Momo's input:
- A weapon that evolves across three forms (gold, green, purple) with different attack patterns
- Chain reaction mechanics where high combos trigger cascading lightning kills
- A phase-shifting ghost enemy that teleports between visible and invisible states
- A three-phase boss fight with escalating attack patterns and minion summoning
- A full procedural soundtrack in pentatonic A minor
- A blink-dash with afterimage effects

None of this was planned. It was divined from Momo's keystrokes.
