Carnivorous plant beside the target - Let players observe a creature’s behaviour before a dangerous experiment. - [Bulletstorm](https://gamemechanics.org/patterns/feeding-enemies-to-creatures) ## How it works The player gains opportunities through understanding other people's behavior. This group is especially well represented in Toki Tori 2+: the developers propose to study the behavior of creatures and control them by whistling and stomping. Description of Two Tribes. ## Variants ### Variants and applications - Attraction and repulsion. Knowing the reaction to sound, light, smell or movement allows you to guide creatures - Limitations of perception. Detecting what a creature sees, hears, and ignores reveals safe routes - Predator and prey. Relationships between creatures are used to open passages or change their location - Feeding and production. Having received a certain resource, a creature creates a useful object, substance or effect - Changing the state of a creature. Sleep, fear, satiety, growth or another stage change its capabilities and reactions - Interaction of several types. The desired result arises from a chain of relationships between different beings - Communication with creatures. The player masters signals, rituals, or sequences of actions that elicit a specific response. ## Context and limits In metroidbrainia, progression depends heavily on the player's knowledge: an open rule changes the available actions, routes, or decisions. 91 mechanics in 12 groups, progression techniques, training techniques and edge cases are stored here. For a project, check what knowledge is acquired, how it is derived, what it reveals, and where it is reused. Specific game solutions are not disclosed. ## Connected materials ## Sources and provenance Original editorial design catalog consolidated from project discussions on 2026-10-20.
