#০২ ⇒ এবার এই কোডগুলো একটি .html ফাইলে পেস্ট করে সেভ করুন। চাইলে .html ফাইলটি ওয়েব সার্ভারে আপলোড করতে পারেন।

নিচে কিছু ডেমো ফটো দিলাম দেখুনঃ

অনেক সহজ ছিলো তাই না? গেইমটি খেলে দেখুন, কেমন লাগে। যদিও এটি হাই লেভেল গেইমের মতো ফিল দেবে না। তবুও আপনার তৈরী প্রথম গেইম হিসেবে ভালোই বলা চলে। গেইমটি যখন আপনার বন্ধুরা খেলবে আর আপনাকে বাহবা দেবে, তখন কেমন ফিল হবে বুঝতে পারছেন? আপনি ভাবতে থাকুন, আমি পোস্টটা শেষ করছি। খোদা হাফেয।
