Stop Drop Pizza
Stop Drop Pizza is a hypercasual mobile game where players deliver towering stacks of pizza boxes while maintaining balance on a moving scooter. Built in Unity, the project focused on physics-based stacking mechanics, responsive controls, and short-session gameplay loops that escalate in difficulty as deliveries grow larger.
Problem
Physics-based stacking games require careful tuning to feel challenging but fair. The challenge was designing a system where pizza stacks become progressively harder to control without causing unpredictable physics behavior that would frustrate players.
Constraints
- Full gameplay implementation in Unity based on a predefined design concept
- Stacking physics needed to remain stable while box counts increased
- Gameplay sessions needed to remain short and intuitive for hypercasual audiences
- Performance had to remain consistent on lower-end mobile devices
Approach
Physics-Based Stack System
Implemented dynamic stacking mechanics where pizza boxes are added to the player's load and react to movement using Unity physics.
Balance and Movement Mechanics
Designed player movement and stack stability systems that require players to adjust speed and direction to maintain balance.
Delivery Gameplay Loop
Created a simple gameplay loop where players collect pizzas, deliver them successfully, and earn rewards based on stack stability and delivery accuracy.
Difficulty Scaling
Implemented progression systems where stack height and environmental obstacles gradually increase the challenge.
Implementation Highlights
