Love the Concept but do not understand "play" – Raising Ojipockle Review

This app is such a cute concept. My concern/issue is that outside of some beginner narrative guidance we are left without game play information-at least information written in English. I have one Ojipockle.... I feed him. I "rub" (???) him and hearts spring forth from him, but that's about it. I tried to play the game to find coins and I could only tap on one coin. The only other coin I saw wouldn't pick up. So I don't really know how to earn coins to buy things... Any help?
