Free the key

The player will be challenged with a puzzle in which he must remove the key through a special passageway in the game area. The game area, on which the block with the key is located, is filled with other blocks that interfere with the movement of the key. There is also a passageway through which the block with the key must be removed to win. The difficulty is that you can't just remove all the interfering blocks. You can only move them around in a limited space to make room to move the right block with the key. These movements are also limited, because depending on the orientation, the blocks can only be moved in one plane: vertically placed blocks move only up and down, and horizontally to the right or to the left. So you have to think hard to solve the problem. Look at the playing field, assess the situation and begin to act. The game is reminiscent of the well-known game of "Frisky". After finishing one level, you can start the next one. Gradually the task will be more difficult and you will need to think even better. The first damage will not cause problems, but the more difficult it will be to get the block with the key. The game has a total of 40 levels, and not everyone can pass the last one. Demonstrate your logical and analytical skills. The number of moves made will be recorded and displayed in a menu with levels. Try to solve this difficult, but very fascinating puzzle.
