Implementing a Tetris game with a horizontal movement blocker. I’m checking the existing project structure first so I can fit it into the current app cleanly.

{"planMarkdown":"## Plan\n- Inspect the current app structure and identify the entry points for a browser-based game.\n- Implement a playable Tetris loop, rendering, controls, scoring, and a horizontal arrow blocker mechanic.\n- Verify the build or test command still passes and note any remaining risks.","subtasks":[{"title":"Inspect app structure and runtime entry points","status":"doing"},{"title":"Build Tetris gameplay and blocker mechanic","status":"todo"},{"title":"Run available verification and review risks","status":"todo"}]}The workspace is minimal: a single index.html and README.md. I’m reading the current app file now and will wire the game directly into it unless there’s an existing structure to preserve.I’ve confirmed the app is a single self-contained HTML game. I’m replacing the current Snake implementation with a full canvas Tetris build and adding a visible horizontal-arrow jam mechanic that intermittently disables left, right, or both horizontal inputs.The implementation is in place. I’m doing a quick static verification pass now: checking the generated HTML/JS for parse errors and reviewing the blocker logic and restart flow for obvious regressions.The script parses cleanly. I’m pulling line-numbered references now so the close-out can point to the actual gameplay and blocker sections instead of giving you a vague summary.Replaced the single-page Snake app with a self-contained Tetris implementation in index.html. The new build includes the game loop, tetromino bag/randomizer, line clears, score/level progression, ghost piece, preview panel, pause/restart handling, and the horizontal arrow blocker mechanic that periodically disables left, right, or both horizontal moves with matching HUD and board feedback in index.html and index.html.

Verification was limited to a static parse check: node successfully compiled the inline script with no syntax errors. I did not run a browser-based playtest in this environment, so gameplay feel and balance of the blocker timing still need manual validation.

{"reviewMarkdown":"## Post-review\n- Replaced the previous single-file Snake game with a canvas-based Tetris implementation and responsive HUD in /home/user/workspace/agent-test/index.html.\n- Added core gameplay systems: seven-bag piece generation, movement, rotation with simple wall kicks, soft drop, hard drop, line clearing, scoring, leveling, ghost piece, next-piece preview, pause, and restart.\n- Added the horizontal arrow blocker system that cycles between idle and active states, randomly blocks left, right, or both horizontal directions, and surfaces its state in both the side panel and board overlay.\n- Tests run: static JavaScript parse check via node -e against the inline <script> block; result was successful.\n- Risks: no interactive browser playtest was possible here, so blocker timing, rotation edge cases, and general gameplay tuning should be manually exercised in a browser."}
