Description
The current game (if undo exists) typically allows only a single undo, limiting flexibility for players who accidentally make multiple misclicks. This restriction can frustrate both casual and strategic players who wish to experiment with different move sequences.
🎯 Proposed Solution
- Extend undo capability to store and revert the last 3–5 moves.
- Maintain a stack of previous game states (board, score, move count).
- Implement keyboard shortcut (e.g., Ctrl + Z) or on-screen Undo button.
- Limit undo count per game (configurable setting to avoid abuse).
✅ Expected Behavior
- Players can revert multiple consecutive moves.
- Undo is smooth, instantaneous, and doesn’t affect game performance.
- Undo history resets when a new game starts.
💻 Technical Notes
- Use a stack data structure to store snapshots of game states.
- Each state includes: tile positions, score, and move history.
- Manage memory efficiently — discard old states beyond the limit.
🧪 Test Steps
- Play a game and make several moves.
- Press Undo repeatedly → verify previous states restore correctly.
- Ensure score and animations revert as expected.
- Start a new game → undo history clears.
