This is a classic "Snake" game enhanced with new features:

• Bonuses (acceleration and slowdown)
• Mines (bombs) with a timer and explosion animation
• Obstacles on the field

There are two types of bonuses:

1. Acceleration (ACCELERATION)
   When eaten, the snake temporarily moves faster (FPS is increased).

   • Displayed as a yellow cube on the field.
   • The duration of the effect is controlled by the BONUS_DURATION parameter.

2. Slowdown (SLOWDOWN)
   When eaten, the snake temporarily moves slower (FPS is decreased).

   • Displayed as a cyan cube on the field.
   • The duration of the effect is the same BONUS_DURATION.

After the snake eats a regular snack (green food), there is a certain chance (MINE_APPEAR_CHANCE) that a mine will spawn (up to MINE_MAX_COUNT = 3 mines).

• The mine is placed on a free cell at least MINE_REQUIRED_DISTANCE away from the snake’s head.
• Each mine has a lifespan (MINE_LIFETIME_TICKS = 120 ticks, ~12 seconds at 10 FPS). When its time runs out, it explodes.
• When the mine explodes, an animation is displayed (expanding circle). If the snake’s head is within 1-cell radius of the explosion, the snake loses (game over).
• If the snake steps on the mine before it explodes, that also results in a game over.

Several (by default OBSTACLE_COUNT = 10) gray "cubes" are placed randomly on the field. If the snake collides with any obstacle, it’s game over:

• The final score (snake length) is displayed.
• The snake is reset to its starting state.
