Picture Block Puzzle 2D | Game Template + Level Editor

Picture Block Puzzle 2D is a complete Unity game template for building and customizing sliding picture-assembly puzzle games. Developed with the HyperCasual Game Engine, this asset provides the core systems, architecture, and tools needed to create a unique mobile-ready puzzle experience.

Players drag color-coded image pieces across a 2D grid to reconstruct original pictures before the timer runs out. With physics-based sliding, multi-cell shape footprints, and satisfying assembly mechanics, this template offers a polished hyper-casual gameplay loop inspired by popular mobile assembly puzzles.

This game template includes a full puzzle gameplay loop, a time-pressure countdown system, three boosters, and a fully featured Unity level editor with automatic level generation. Every system is modular, data-driven, and designed as a foundation for rapid extension and production-ready development.

TEMPLATE INCLUDES

🖼️ Picture-Assembly Gameplay

· Slide-to-Assemble Mechanic: Drag-and-drop pieces on a 2D grid with physics colliders to prevent overlap.

· Multi-Cell Shape Footprints: Support for complex block shapes that occupy multiple grid cells.

· Zero-Piece Anchor System: Solved states are computed relative to a designated anchor piece for precise assembly.

· Picture Merge Effect: Pieces fade into the final image with star particle bursts upon successful completion.

· Time-Pressure Countdown: Customizable per-level time limits that trigger lose conditions at zero.

· Obstacle System: Static wall cells that blocks cannot enter, adding strategic depth.

🏗️ Level Editor & Data System

· Visual Grid Painter Window: Dedicated Editor tool for painting obstacles, blocks, and sprites without entering Play mode.

· Auto Level Generator: Batch-generate hundreds of playable levels with configurable difficulty, grid size, and color counts.

· JSON Level Format: Levels are stored as scannable JSON files, making content easy to manage and extend.

· Block & Sprite Management: Per-piece sprite selection from Resources and per-block color assignment.

· Idempotent Setup Wizard: Project health check tool to verify scene settings, audio, and URP requirements.

🎮 Boosters & Gameplay Systems

· Three Built-in Boosters: Time Freeze (pauses clock for 10s), Hint (previews a piece's solved position), and Shuffle (randomly reseats blocks).

· First-Use Tutorial Popups: Automated UI prompts that explain booster mechanics to new players.

· Unlock System: Level-gated booster availability (e.g., Hint at Level 2, Shuffle at Level 3).

· FrozenImage Indicator: Visual feedback that signals when the Time Freeze booster is active.

🎨 Customization & Visual Tools

· Modular UI System: Includes HUD panels, Win/Lose screens, and booster-use badges.

· Portrait/Landscape Support: Features a CameraSwitcher for swapping presets based on orientation.

🧪 Developer & Debug Tools

· In-game Dev Settings Panel: Quick-access menu for level navigation, win/lose triggers, and ad testing.

· Global Hotkeys: Use 'U' to unlock boosters or Arrow keys for instant level skipping during testing.

· Clean Codebase: Utilizes singleton SoundManager and GridManager for reliable scene orchestration.
