Creation History
User prompt
Play a very short and pleasant sound effect every time tiles merge. Include a toggle button in the UI that allows the user to mute or unmute these merge sounds anytime.
User prompt
Please fix the bug: 'Cannot set properties of undefined (setting 'font')' in or related to this line: 'return "'GillSans-Bold', Impact, 'Arial Black', Tahoma, sans-serif";' Line Number: 99
User prompt
Enhance the tile numbers by rendering them with a stylish font that includes soft shadows or subtle outlines to improve readability and visual appeal. Ensure the shadows adapt dynamically to tile colors for good contrast.
User prompt
For each tile value, use a unique visual asset (e.g., different colored or patterned squares) instead of just coloring the tile. Implement a system that assigns the correct asset based on the tile's numeric value and updates the displayed asset whenever the tile value changes.
User prompt
Ensure each tile's background color changes dynamically based on its numeric value. Lower numbers (like 3) get lighter, pastel colors. Higher numbers get progressively darker or more vivid colors. Please implement this coloring logic so tile colors update whenever their values change.
User prompt
Modify the game logic so that if any tiles merge during a move, no new tile is spawned afterward. Only spawn a new tile if no merges happened in that move.
User prompt
Assign a unique background color to each tile value. The smallest tile (3) should have the lightest/most faded color. Colors become progressively more vivid and eye-catching as tile values increase. The largest tile should have the most vibrant and standout color.
User prompt
Implement smooth sliding animations for tiles after each move, similar to the classic 2048 game. Tiles should visually glide from their original positions to their new positions before merging or settling. ↪💡 Consider importing and using the following plugins: @upit/tween.v1
User prompt
lease redesign the game logic to follow classic 2048 rules: Tiles slide fully in the chosen direction until they hit another tile or edge. Tiles merge only once per move when two identical tiles collide, producing their sum. After each move, spawn exactly one new tile (3 or 6) in a random empty spot. Allow moves in all four directions regardless of empty spaces. Continue until no moves are possible.
User prompt
If there are empty spaces in a column or row, the player should be able to slide tiles up, down, left, or right to fill those spaces. Currently, moves are blocked if empty spaces exist in the middle. Please fix so that tiles can slide over empty cells in all directions.
User prompt
After each move, the game must spawn only one new tile with value 3 — but only if no merges happened during that move. Ensure it never spawns more than one tile per move.
User prompt
If any tiles merge during a move, the game should not spawn a new tile with value 3 after that move.
User prompt
Ensure that only adjacent tiles with the same value merge by adding their values. Tiles should merge even without empty spaces between them if the move causes them to collide. All possible merges in a single move must be processed.
User prompt
Currently, tiles only merge if there is an empty space to move into. For example, when the column is [3, 3, 6, 12] and the player moves down, the two 3s don’t merge because there is no empty space below. Please fix the logic so that tiles with the same value merge even if no empty space is available, as long as the move direction would cause them to collide.
User prompt
The current merge logic only merges newly added tiles but ignores existing tiles on the board. Please fix the merging algorithm so that all tiles on the board, both old and new, are checked and merged correctly if they have the same value during a move.
User prompt
In the current game, when multiple pairs of identical tiles (e.g., several 3s) can merge in a single move, only one pair merges. Please update the logic to scan the entire 4x4 grid and merge all possible pairs of matching tiles in that move.
User prompt
There is a bug in the merge logic: when two tiles with the same value (e.g., two 3s) are stacked and moved, they do not merge into their sum (6). Please check and fix the merging function to ensure that tiles with the same value combine correctly by adding their values.
Initial prompt
Implement the game over condition: the game ends when there are no possible moves left.

Design a background similar to the original 2048 game. Use a warm, soft beige or light brown tone as the main background. Include a grid layout with rounded square slots where tiles appear. Each slot should have a slightly darker shade than the background to show the empty grid clearly. Keep the overall design minimal, clean, and visually balanced.. In-Game asset. 2d. High contrast.
