1) The direction meter has been positioned as a tutorial.
The directional meter implemented in v1.1.0 was introduced to make the rules of the game easier to understand for first-time players.
However, this caused the game to become easier than the intended difficulty level, so in order to position the direction meter as a tutorial only, the direction meter was modified to be destroyed and unusable in the middle of the game.

2) Types of light bulb colors
Changed the color type of the bulb from 2 to 3.
