Code Review

This pull request introduces a new web-based game called "Dolphin Butter Splash," including its core logic in JavaScript, HTML structure, and CSS styling. It also updates the main games page to include a link to the new game. Feedback focuses on fixing HTML syntax errors and accessibility attributes in the game card, as well as optimizing the game's rendering and logic by reducing redundant canvas state changes and streamlining array iterations for item updates and collision detection.

The alt attribute for the Dolphin Butter game image is incorrectly set to "Alge-Blast". This should be updated to accurately describe the game for better accessibility.

There is an extra closing </p> tag here which should be removed to ensure valid HTML.

The ctx.fillStyle is set to the same value in every iteration of the loop. Moving it outside the loop improves performance by reducing redundant state changes in the canvas context.

Suggested change

	for (let i = 0; i < 6; i++) {
	ctx.beginPath();
	ctx.fillStyle = 'rgba(255, 255, 255, 0.35)';
	const waveY = 30 + i * 90 + Math.sin((state.frame + i * 50) / 30) * 12;
	ctx.ellipse(450, waveY, 260, 22, 0, 0, Math.PI * 2);
	ctx.fill();
	}

The collision check for rocks continues even after a collision is detected. Using Array.prototype.some() is more efficient as it will stop iterating as soon as a collision is found.

  const collision = state.rocks.some((rock) => 
    rock.x < hitbox.x + hitbox.w && rock.x + rock.size > hitbox.x && rock.y < hitbox.y + hitbox.h && rock.y + rock.size > hitbox.y
  );
  if (collision) state.gameOver = true;

The updateItems function iterates over the butter and rocks arrays twice. These operations can be combined into a single filter pass for each array to improve performance.

Suggested change

	state.butter.forEach((butter) => (butter.x -= butter.speed));
	state.rocks.forEach((rock) => (rock.x -= rock.speed));
	state.butter = state.butter.filter((butter) => butter.x + butter.size > -20);
	state.rocks = state.rocks.filter((rock) => rock.x + rock.size > -20);
	state.butter = state.butter.filter((butter) => {
	butter.x -= butter.speed;
	return butter.x + butter.size > -20;
	});
	state.rocks = state.rocks.filter((rock) => {
	rock.x -= rock.speed;
	return rock.x + rock.size > -20;
	});
