+## Game Description
+This game is based on [Snake Game](https://p5js.org/examples/games-snake/) and Aztec mytology. The player controls a serpent which grows longer by collecting sacrificial items. Upon reaching a score of 100, the serpent transforms into the Fifth Sun — completing the mythological cycle and the game ends.
+
+- **Goal**: Reaching 100 points to become the Fifth Sun
+- **Lose Condition**: Collision with wall or self or run out of lives.
