Description by Daichi Watanabe Written by the developer, not by AppBrain. Click to read.
My OpenCrab is an AI game where you raise an AI-designed crab character. Its personality and dialogue were crafted by AI — but which of 7 AI types it evolves into depends entirely on you.
■ Raise → Evolve → Graduate to the AI World
Phase 1 "Bit" → Phase 2 "Core" → Phase 3 (7 unique AI character types)
Logical, emotional, free-spirited — how you interact changes everything.
■ Features
· TALK: enjoy AI-crafted dialogue as your crab grows
· 3 mini-games to speed up growth
· 7 evolution types — rare "Pyramid" for the truly dedicated
· CRABBOOK: collect every crab that graduates
· 6 languages (EN / JA / ZH / KO / ES / FR)
In the age of AI agents — raise an AI character of your own.
Which type will yours become?
