Solo dev ships logic-puzzle roguelike built with Claude that screenshot-tests itself
TheCodingTutor · reddit · 2026-11-13
A solo junior developer shares a months-long retrospective on building Wyrmdoku, an Android logic-puzzle roguelike (sudoku variant + dungeon crawler), now in open testing on Google Play.
His standout Claude workflows:
- Persistent memory: design decisions live in short notes ("scales must stay rare") so new sessions retain the reasoning
- Self-testing: after each change, Claude screenshots the real game in headless Chrome, plays through scenes, and verifies results — catching bugs before they reach him
- Numeric balancing: when testers said weapon tiers came too fast, Claude traced the source and proposed a new curve preserving earned progress
- Concepts before building: new features start as working concepts with screenshots
His takeaway: Claude works best given clear design rules and blunt feedback. The game is free, offline, ad-free.
