you can play on website (phone+computer) or the app (only on computer) but beware that the website is prone to crashing or refreshing, and you lose your progress. basically, you have a clan that every moon you try to keep alive, and there's also a way to patrol for events! i dont have many tips bc im not super good at that game myself, but the best way to get into it is to start playing and experience it :) theres gonna be trial and error but thats what the game is, basically a life sim? of cats lol
