I want to tell you about Celestial Dragon Mastery 🐉⚡️. It is a game that I submitted for the Easy Lens Challenge, which is also known as #easylenscontra.
In this game, you get to be in charge of the sky guardians. It is a cool interactive game that uses something called AR, which is like a special kind of technology.
You can change how you look and control a dragon that is made of crystal. You can do all of this by using your hand.
Here are some of the things that you can do in the game:
You can use something called Face ML Transformation to turn into a dragon that's like a guardian. This dragon is really cool. Has bright neon lights on it.
You can use Precision Hand Tracking to put a detailed dragon on your hand. This dragon is made of crystal. It glows.
You can play the game in a way that's interactive and in the real world. You have to move your dragon around to avoid getting hurt by things that are trying to stop you. You also have to collect balls that have energy in them.
You can control your dragon by making faces.
For example, if you open your mouth, your dragon will breathe fire. This can help you get past things that're in your way.
If you raise your eyebrows, your dragon will get a shield that can protect it.
The game also has a display that shows you how you are doing. It is like a screen that you can see while you are playing.
When you win the game, you get to see a cool effect that is, like a big celebration. You can even take a picture of yourself with your dragon at the end.

Some quick tips on how judges are scoring 📋
Judges score every entry on four things:
1️⃣ Creativity + originality
2️⃣ Best use of a Tool (games, face gen, Video Transform)
3️⃣ Lens+ performance
4️⃣ We review every submission, so we can tell when a Lens is a remix of someone else's entry. Those remixes just won't carry much weight on creativity and originality, and that's a full quarter of the score.
Original ideas get the most weight. You've got until August 4, 11:59pm PT. Plenty of time to build something only you would think of.
Explore. Play. Create.
🕹️ What I Built
I created Neon Byte Runner, a fast-paced retro arcade game Lens for Snapchat inspired by classic endless dodgers and 80s neon aesthetics. Built entirely using prompt-based iteration in EasyLens, the game includes:
Procedural Pixel-Art Visuals: Glowing neon ships, data bugs, energy bytes, and background scanlines drawn in real time for crisp rendering across all screen sizes.
Drag-and-Dodge Controls: Intuitive mobile steering where players dodge incoming "data bugs" and collect "energy bytes" for score multiplier points.
Dynamic Damage System: A three-life mechanic where taking damage physically breaks off spaceship parts (wings and tail) with visual particle flares.
Magical Heart Repairs: Rare falling heart powerups that grant an extra life and visually repair broken spaceship parts back onto the ship.
Chiptune Audio & Global Leaderboard: Custom-generated arcade music and sound effects paired with an integrated HUD and leaderboard to drive replayability.
💡 Why I Built It
Reimagining Classic Arcade Mechanics for AR:
I wanted to capture the instant-play energy of old-school arcade cabinets and adapt it into a social, mobile-first Snapchat Lens. The goal was to create a game that takes seconds to learn, but offers enough depth and escalating difficulty to keep players saying, "Just one more run."
Visual & Emotional Damage Feedback:
Instead of relying on a standard health bar, I wanted players to feel the stakes. Making the ship parts physically break off and scatter across the screen creates an immediate, dramatic feedback loop when you make a mistake—and grabbing a rare heart to repair your ship feels genuinely rewarding.
Pushing the Boundaries of Prompt-Based Game Design:
As a developer, I wanted to explore how far prompt engineering inside EasyLens could go. I set out to prove that you can build complete, highly polished game systems—including state management, procedural rendering, sound synthesis, and dynamic damage states—purely by guiding AI with precise multi-step prompts.
✨ How EasyLens Made It Possible
Using EasyLens, I didn't need to hop between traditional 3D software, external audio workstations, or manual script compilers. I iterated through targeted prompts to handle:
Generating procedural visual assets on the fly.
Setting up custom arcade music and dynamic sound triggers.
Fine-tuning game controls, collision boxes, and damage states.
EasyLens handled the heavy lifting, allowing me to focus on game feel, pacing, and player experience
I wanted to create a transformation that feels like stepping into a blockbuster fantasy movie instead of simply wearing a digital mask. The goal was to let users experience the power of becoming the legendary Dragon King while keeping their own identity and expressions visible. By combining realistic facial morphing with an immersive volcanic world, the Lens delivers a cinematic experience that is dramatic, magical, and highly shareable. Every interaction is designed to make users feel powerful and encourage them to create and share unique videos.
