Improved Game AI and Gameplay
- Skeleton
- The skeleton is a new enemy with two states (walk, attack). In the walk state, the enemy moves toward the player and plants. When they are in range, the enemy will transition to the attack state and fire an arrow. Regular zombies are unable to harm plants.
- Plant
- Press "f" to plant a seed in farmland. After a certain amount of time, seeds will mature into plants with two states (idle, attack). In the idle state, if there is an enemy on the map, the seed will transition to the attack state and fire a projectile. The player can obtain new seeds from levelling up
