A classic Pac-Man clone built in Go using Ebitengine. All sprites, sounds, and fonts are generated programmatically — no external assets required.
Game was made for testing obra/superpowers in Claude Code. Except for input and slight guiding during the brainstorming part of superpowers, I left all planning and execution up to Claude (just accepting any suggestions).
I'm on the small Pro-plan and quickly ran out of tokens and reached my quota and limits. After brainstorm, planning and implementing
2 of 14 steps I had to wait 5 hours for quota reset.
After implementing step 13 of 14 I hit a new limit and I had to wait 2 days to continue (sic).
So the project took two days to complete on Pro-plan, but the actual time spent with the agent was probably around 1 hour.
go run main.goPress Space to start. Use arrow keys or WASD to move Pac-Man.
- Eat all dots to clear the level
- Power pellets turn ghosts blue — eat them for bonus points (200, 400, 800, 1600)
- Ghosts cycle between scatter and chase modes
- Difficulty increases each level (faster ghosts, shorter frightened duration)
- Extra life awarded at 10,000 points
- Design Document — brainstorming and architecture decisions
- Implementation Plan — 14-task TDD implementation plan
14 features implemented across 17 commits:
- Maze rendering, Pac-Man movement, ghost AI, collision system, sound effects, HUD, game state machine, difficulty scaling, tunnel wrapping, death animation, blinking pellets, extra life
3 bugs fixed during playtesting:
- Ghosts re-entering ghost house through the door (blocked ghost door/house tiles for active ghosts)
- Ghosts stuck in place due to float64 tile center oscillation (added
lastDecisionTiletracking) - PacMan not responding to input when stopped (allow re-processing tile center when
Dir == DirNone)
27 tests passing, all programmatic (no external assets).
