About this game

**Zoo Crush — Swipe, Match, Rescue**

Zoo Crush is a lightweight animal-themed match-3 puzzle built for short, replayable sessions. The core loop is simple: swipe to swap neighboring animals, form lines of 3 or more, rescue animals, and chain cascades for bigger combos before you run out of moves or time.

**Gameplay**
- A 7×7 board with 6 animal friends is the main play field
- Swapping two adjacent animals forms matches of 3 or more
- Each clear rescues animals and adds score
- Cascading drops and refills can trigger combo chains with bonus scoring
- A run ends when the rescue goal is reached or moves/time run out

**Goals & Limits**
- Default move limit of 30 per run
- Optional countdown timer of 180 seconds (toggle in Settings)
- Rescue goal of 24 animals to win the level
- Dead boards auto-normalize so a valid move always exists

**Assist Systems**
- Hint: highlights a strong move (rewarded ad)
- Shuffle: reshuffles the board once (rewarded ad)
- Undo: reverts the last move, limited free uses per run
- Rewarded ads can unlock Hint and Shuffle when you are stuck

**Player Feedback**
- Smooth tile movement, spawn, and swap animations
- Combo pop, score bump, and timer warning effects
- Invalid-move shake and dead-board prompts
- Haptic feedback follows the vibration setting

**UX Notes**
- Pure multi-Activity navigation, no bottom tab structure
- Custom title bar on secondary pages
- Edge-to-edge adaptation for status bar and bottom system area
- Pause stops the timer and board interaction; backgrounding auto-pauses

**Ad Integration**

- Interstitial ads: game-over and game-exit transitions
- Undo is a free per-run boost and does not require ads
