Dungeons, drama, and a robot intern
Letting AI play my game – building an agentic test harness to help play-testing
This indie dev let AI test his dungeon game, and the comments instantly turned into a sleep-deprived game lab
TLDR: A game developer built a way for AI to play his crossword-themed dungeon game and help find bugs without changing the real game itself. Commenters loved the idea, but also instantly argued over whether AI is genius here or just a flashy substitute for simpler automated testing.
An indie developer showed off a wild little breakthrough: instead of personally slogging through endless test runs of his browser game, he built a way for AI to actually play it in a stripped-down text view and help catch bugs. The game, Crossword Dungeon, is already delightfully odd — part crossword, part dungeon crawler — and the crowd was immediately charmed. One commenter basically opened with, "forget the testing drama, I just want to play this when I get home," which is honestly the strongest compliment in the room.
But the real fun started when the community did what communities do best: turn one cool demo into a mini debate club. One side was impressed that the AI could wander the dungeon, shop, fight monsters, and stumble in the same places human players do. The other side came in with the classic "okay, but do you even need AI for this?" energy, arguing a plain simulator could blast through thousands of fake games faster. That sparked the hot take of the thread: is this clever play-testing, or just a very entertaining way to reinvent automated testing?
Meanwhile, several fellow game makers piled on with their own late-night goblin energy, bragging that they too have AI testers now — some even send them off to fix bugs while they sleep. Yes, the vibe quickly became: why suffer through testing yourself when your tireless robot intern can do the dungeon crawl at 3 a.m.? Equal parts ingenious, chaotic, and a little bit "the future is weird."
Key Points
- •The developer built an AI-assisted play-testing approach for the browser game Crossword Dungeon to reduce manual testing of the live game system.
- •Crossword Dungeon combines crossword puzzle mechanics with dungeon-crawler gameplay, where letters function as rooms containing encounters and solving clues changes dungeon difficulty.
- •The developer decided against screenshot-heavy browser automation and instead used a text-oriented approach better suited to a turn-based, text-heavy game.
- •An AI-generated Node.js wrapper added a text renderer and synthetic event inputs without modifying the original game files.
- •The harness lets the AI play the same underlying browser game logic through terminal snapshots and stateless HTTP calls, enabling bug reproduction and edge-case testing.
