Stainless Steel 2048

Inspired by the skeuomorphic design in the early 2000s, I developed this 2048 - like game.
This game not only incorporates the traditional mechanism of adding two equal numbers together but also adopts the mechanism that allows all numbers in a geometric sequence to be added up. If the first two numbers in a row of numbers, after being added together, make the entire row of numbers form a geometric sequence, then all the numbers in that row can be added up. If there is an even number of completely equal numbers in a row, they can also be added up entirely, and then the score is calculated according to the number of addition operations.
The game contains four different scenes, and the edge length can be set for each scene.
The game includes a subtraction mode and a countdown mode.
In the game, each operation will add a number, and the situation may vary depending on the different edge lengths.
In the subtraction mode, each operation will add one more number than in the normal mode. In the countdown mode, the player's score can be used to extend the time.
In the game, if all the grids are filled with numbers and the player's operation does not result in the addition or subtraction of numbers, regardless of whether it is still possible to add or subtract from other directions, the game will end.
Seven different skills have also been added to the game. As the player's score increases, they can obtain the right to use the skills, and the skills can be activated by clicking the button on the right side of the game grids.
The skills are as follows: randomly subtract one number, go back to the previous step, randomly readjust the positions, add up most of the numbers at one time, use the mouse to delete one number, use the mouse to freeze one number (this number can be unfrozen when it is added to or subtracted from by other numbers), and use the mouse to swap the positions of two numbers.
The game supports customizing the keyboard and mouse buttons, and the key bindings can be changed in the settings.
