Build a playable Space Invaders game on a canvas: a player cannon that moves and shoots, a descending grid of aliens that advance and fire back, destructible bunkers, score, and lives. Procedural graphics only, no external assets.
<thinking>The task requires creating a playable Space Invaders game with procedural graphics. I need to build an HTML file that includes HTML, CSS, and JavaScript to handle the game logic and rendering. I'll need to define the game elements such as the player cannon, aliens, bunkers, and the game loop. Since this is a complex task, I'll break it down into steps and implement them one by one.</thinking> <thinking>I have created the basic structure of the Space Invaders game with procedural graphics. The next step is to add more features like alien movement, alien shooting, and the logic for the game to advance and end. I'll need to expand the JavaScript code to include these features.</thinking> <thinking>I have added alien movement, alien shooting, and the game loop logic to the existing JavaScript code. The next step is to test the game and ensure all features are working as expected.</thinking>

EVALUATION
Game shows immediate 'Game Over' with score 0; no player cannon visible and no response to any input.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
