Jian Gainsan
Add lands, make the game like dragon city. Instead of changing materials into foods, add boilers in the land and you can cook food there in exchange for tus. And also add some things you can build on the land, somewhere that crabs can fuse or breed in exchange of tus also. Add some pets that will clean the city and add other mini games in crabada like crabs racing and etc. And also you can collab woth movies, series to design crabs. Add fusion too, skins of crabs and more.
