ArrowPath

Arrow Path is a 3D cube puzzle game. Players tap cubes marked with directional arrows to make them fly out and be eliminated. The goal is to clear all cubes from each level.

## Core Gameplay

### Basic Rules

1. Cubes & Arrows: Each cube has an arrow pointing in one of six directions (Up, Down, Left, Right, Forward, Backward).
2. Tap to Eliminate: Tap a cube, and it will fly out in the direction its arrow is pointing.
3. Collision Handling:
- If the flying cube collides with another cube → it returns to its original position
- If two cubes have opposite arrows (Up↔Down, Left↔Right, Forward↔Backward) → their direction values swap (arrows rotate)
- If no collision occurs → the cube is eliminated (removed from the scene)
4. Win Condition: Clear all cubes in the current level.

### Level System

- 10 levels total, with increasing number of cubes
- Each level has a countdown timer — if time runs out, you fail
- Star rating (1–3 stars) is awarded based on remaining time — more time remaining = more stars
- Best completion time is recorded after finishing Level 2
