Level Design & Game Progression
The game features 50 levels split into three progressive sprite phases.
🐧 Penguin Phase (Levels 1-10)
Levels 1 to 10 introduce tiles with Tux penguin faces exclusively (drawn from face IDs 0 to 49). The board size ramps up gradually from a quick 36-tile board up to the full 144-tile layout at Level 10.
- Level 1: 36 tiles (9 distinct faces)
- Level 5: 84 tiles (21 distinct faces)
- Level 10: 144 tiles (36 distinct faces)
🐶 Dog Phase (Levels 11-20)
Levels 11 to 20 repeat the tile counts (36 to 144) but mix dog styles into the sprite pool. Each new level introduces one additional dog style (10 variants per style) until 5 styles are active at Level 15-20.
- Level 11: 36 tiles (Tux + 1 Dog Style)
- Level 13: 60 tiles (Tux + 3 Dog Styles)
- Level 15+: 84-144 tiles (Tux + 5 Dog Styles)
🚀 Space Phase (Levels 21-50)
Levels 21 to 50 combine penguin, dog, and space-themed tiles. The face pool size scales from 100 up to 200 distinct faces, and tile counts cycle from 36 to 144 every 10 levels.
- Level 21: 36 tiles (100 Face Pool)
- Level 30: 144 tiles (131 Face Pool)
- Level 50: 144 tiles (200 Face Pool)
