Summary of Changes

Hello @bkhiemm, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new standalone HTML file that serves as a basic interactive web game. The game, themed around 'Jujutsu Kaisen', allows users to engage in a simple boss battle by selecting different attack moves, which then dynamically updates the boss's health and provides real-time feedback on the game's state.

Highlights

• New File Creation: A new HTML file named JJk.html has been added to the repository.
• Jujutsu Kaisen Game: The newly added JJk.html file implements a simple, interactive web-based game inspired by 'Jujutsu Kaisen', featuring a boss battle.
• Game Mechanics: The game includes basic mechanics such as a boss HP bar, two distinct attack moves ('Black Flash' with a hit chance and 'Divergent Fist' with guaranteed hit), and dynamic updates to the game status and messages.

Code Review

This pull request introduces a new HTML file for a simple browser-based game. The code is a good starting point, but I've identified a few key areas for improvement in the JavaScript logic. My review focuses on fixing a critical bug where the game doesn't end correctly, improving the user experience by adjusting how messages are displayed, and enhancing code maintainability by suggesting the removal of hardcoded 'magic numbers'. These changes will make the game more robust and easier to build upon.

There are two issues with the game's end state:

1. The attack buttons are not disabled after the boss is defeated. This allows the player to keep clicking them, which repeatedly appends "VICTORY!" messages.
2. Using innerHTML += ... is inefficient for appending elements and can have unintended side effects. It's better practice to create and append a new element using document.createElement() and appendChild().

This suggestion fixes both issues.

            if(bossHP <= 0) {
                const victoryEl = document.createElement('h3');
                victoryEl.textContent = "VICTORY!";
                document.querySelector('#game-box').appendChild(victoryEl);
                document.querySelectorAll('button').forEach(b => b.disabled = true);
            }

The script uses several "magic numbers" and strings (e.g., 100, 'Black Flash', 0.3, 35, 15). Hardcoding these values makes the code harder to read, maintain, and balance. Consider defining them as constants at the top of the script with descriptive names. This will make your game logic much clearer and easier to tweak in the future.

For example:

const BOSS_MAX_HP = 100;
const BLACK_FLASH_HIT_CHANCE = 0.7; // (1 - 0.3)
const BLACK_FLASH_DAMAGE = 35;
// etc.

The victory message ("CHÚC MỪNG! ...") overwrites the message from the final, winning attack. This means the player doesn't get to see which attack finished the fight. It would provide a better user experience to append the victory message to the attack message instead of replacing it entirely.

Suggested change

	if(bossHP <= 0) {
	bossHP = 0;
	msg = "CHÚC MỪNG! Bạn đã thanh tẩy Nguyền hồn!";
	}
	if(bossHP <= 0) {
	bossHP = 0;
	msg += " CHÚC MỪNG! Bạn đã thanh tẩy Nguyền hồn!";
	}
