In this Unity beginner tutorial (Session 57), we upgrade our Wacky Food (Whack-a-Food / Whack-a-Mole style) game by adding a 60-second countdown timer. Instead of ending the game when a good object is missed, we convert the project into a time-based arcade game where Game Over triggers when the timer reaches 0.
✅ What you’ll learn in this session:
How to add a countdown timer in Unity using Time.deltaTime
How to display time using TextMeshPro (TMP) UI
How to reset the timer when the player selects Easy / Medium / Hard
How to update the UI every frame with a clean UpdateTimeUI() method
How to remove old miss-based game over logic from TargetX.cs
How to build and publish WebGL to Unity Play (zip + upload)
🎮 Final result:
Score on the left ✅
Timer on the right ✅
Timer counts down from 60 → 0 ✅
Game Over screen appears exactly at 0 seconds ✅
📌 Project Type: Arcade / Whack-a-mole style
🧠 Skill Level: Beginner friendly
🛠 Tools: Unity, TextMeshPro, C# scripting, WebGL build
