🧠 Overview

Quick Reflex is a fast-paced 2D reaction game built as a Snapchat Lens. It challenges players to respond to rapid on-screen prompts using taps and swipes, testing their reflexes, focus, and timing in short, replayable sessions.

Designed specifically for Snapchat’s social environment, Quick Reflex encourages friendly competition through score sharing, leaderboards, and quick challenges between friends. Players can instantly launch the game by scanning the Snapcode — no downloads or installations required.

Quick Reflex leverages Snapchat’s interactive Lens platform to bring casual, competitive gaming directly into everyday social interactions.

▶️ How to Play

  1. Scan the Snapcode or open the Lens link in Snapchat
  2. Tap Start to begin the game
  3. Follow the on-screen prompts:
  • Tap when instructed
  • Swipe in the correct direction
  • React quickly before time runs out
    1. Each correct action increases your score
    2. The game speeds up as you progress
    3. One mistake ends the run — try again to beat your best score!

At the end of each session, players can:

  • View their final score
  • Compare results
  • Share or challenge friends directly through Snapchat

🕹️ Gameplay Mechanics

  • Input Types: Tap, swipe (up/down/left/right)
  • Session Length: 30–60 seconds
  • Difficulty Scaling: Reaction time windows shrink as the score increases
  • Scoring System: Rewards speed, accuracy, and consistency
  • Replayability: Designed for fast retries and score chasing

💡 Inspiration

Quick Reflex was inspired by:

  • The way people interact with Snapchat in short, frequent bursts
  • Casual reaction games that are easy to learn but hard to master
  • The competitive energy of sharing scores and challenging friends

The goal was to create a game that feels native to Snapchat, rather than a traditional mobile game port.

⚙️ How We Built It

  • Built using Lens Studio
  • Implemented with JavaScript
  • Uses full-screen 2D UI elements

  • Modular game manager for:

    • Game states (Start, Play, Game Over)
    • Input handling
    • Scoring logic

  • Designed to be easily extendable with:

    • Leaderboards
    • Turn-based challenges
    • Persistent storage

No AR camera features were required, keeping the experience fast and accessible.

🧱 Challenges We Ran Into

  • Designing gameplay that works well with touch input inside Snapchat
  • Balancing difficulty so the game feels challenging but fair
  • Optimizing UI clarity on different screen sizes
  • Structuring the project to support multiple tracks without overcomplicating the core experience

🏆 Accomplishments We’re Proud Of

  • A fully playable game published as a public Snapchat Lens
  • Clean, fast gameplay that feels native to Snapchat
  • A simple but addictive core loop
  • Designing for multiple Lensathon tracks with a single project

📚 What We Learned

  • Snapchat is a powerful platform for casual social games
  • Short session design is critical for engagement
  • Clear visual feedback is essential for reaction-based gameplay
  • Building modular systems early makes extending features much easier

🚀 What’s Next for Quick Reflex

  • Add global and friends leaderboards
  • Introduce daily challenges with unique modifiers
  • Expand turn-based challenges between friends
  • Add cosmetic themes and visual rewards
  • Further refine difficulty scaling based on player data
