Frost Forge Puzzle

Frost Forge Puzzle is a tactile 2D sliding number puzzle where players merge arctic rune tiles to discover higher-order crystal structures.

Core Puzzle Mechanics:
- Swipe across the screen horizontally or vertically (Up, Down, Left, Right) to slide all unlocked tiles across the grid.
- When two tiles sharing identical values collide, they combine into a single tile of double value (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048).
- Consecutive merges trigger combo multipliers, awarding bonus score points for chained consolidations.
- Overcome frozen hazard tiles that remain immobile until thawed by surrounding moves or the Thaw power-up.
- Use the Thaw Ice action button at the bottom-right of the screen to unfreeze locked grid slots.
