A kawaii VR game that progressively becomes darker

A unique VR experience where you smash adorable cupcakes with a hammer in a pastel universe that becomes increasingly unsettling as the game progresses.

Cuteness Overdose is a virtual reality game developed for Meta Quest 3 that blends kawaii aesthetics with a creepy atmosphere. The player uses a hammer to destroy randomly appearing cupcakes while progressing through two scenes with distinct atmospheres.

• Objective: Reach 100 points by hitting cupcakes
• Controls: Grab the hammer with Quest controllers and smash the cupcakes
• Progression:
  • GameScene (0-50 points): Kawaii atmosphere with soft music
  • GameSceneIntermediaire (50-100 points): Darker, creepier atmosphere
  • EndingScene: Final scene after reaching 100 points

• 🎯 Dynamic spawning system: 8 positions with 5 cupcake types
• 🔨 Realistic physics: Collision detection with velocity threshold
• 🎨 Visual effects: Cupcake fade-out, impact particles
• 🎵 3D spatial audio: Ambient music and impact sounds
• 📊 Score system: Progress bar and automatic transitions
• 🌈 2 distinct atmospheres: From kawaii to slightly creepy

• Unity: 2022.3.37f1 (LTS)
• Blender: 4.1
• Git: Version control

• XR Interaction Toolkit: 2.5.4
• XR Hands: 1.7.2
• OpenXR: Meta Quest Plugin
• TextMeshPro: UI and text
• XR Device Simulator: Testing without headset

• Meta Quest 3: Primary VR headset
• Quest Link: PC connection for development

• Meta Quest Developer Hub installed (optional, for Quest deployment)
• Developer Mode enabled on Quest (optional, for Quest deployment)

1. Clone the repository:

   git clone https://github.com/your-repo/Cuteness-Overdose-Vr.git
   cd Cuteness-Overdose-Vr

2. Open the project in Unity 2022.3.37f1

3. Verify XR settings:

   • Edit → Project Settings → XR Plug-in Management
   • Check OpenXR for Android and PC
   • Add Meta Quest Feature in OpenXR

⭐ Important: The XR Device Simulator is already configured in the project!

1. Open MenuScene in Unity

2. Click Play in Unity Editor

3. The simulator activates automatically and works throughout the entire game (all scenes)

4. Use keyboard/mouse controls:

   • Tab: Cycle between HMD/Controller/Hand input
   • Right Shift + Mouse: Move right hand
   • Left Shift + Mouse: Move left hand
   • Space + Mouse: Move both hands
   • G: Grip (grab hammer and objects)
   • Mouse Movement: Look around (when HMD is selected)
   • Z, S, Q, D: Move forward, backward, left, right
   • E/A: Move up/down
   • Mouse Scroll: Adjust movement speed

5. XR Device Simulator UI (bottom-left corner):

   • Shows current input mode (Controller/Hand/HMD)
   • Displays button mappings
   • Can be minimized by clicking the arrow icon

Note: Once activated in MenuScene, the XR Device Simulator remains active for all subsequent scenes (IntroScene, GameScene, GameSceneIntermediaire, EndingScene). You don't need to reconfigure it!

• Check that Platform has a Box Collider or Mesh Collider

• Verify the hammer has been grabbed (wait 2 seconds after grab)
• Check Delay After Hammer Grab = 2s in CupcakeSpawner
• Verify all 8 spawn positions are assigned in Inspector
• Check Console for spawn-related errors

• Verify ScoreManager (or ScoreManagerFirstScene) is in the scene
• Verify cupcakes have the Tag "Cupcake" (case-sensitive)
