Bean Beasts focuses on controlling a team of creatures called Bean Beasts in a strategic tower defense. The player places creatures in specific areas to repel monsters while upgrading traps and abilities in different directions. Each level introduces new enemy types with unique movement patterns, requiring a change in placement and tactics. At the end of a series of waves, boss fights occur, where it is important to use resources wisely and synchronize actions. Upgrading the Beasts unlocks additional skills that affect their combat behavior and effectiveness.
