Great but... – Winx Club Butterflix Adventure Review

I love this game so much but the problem is I don’t know how to get keys. it’s really hard and I really wanna play as different characters. I’ve been through some places and I still can’t find any keys or so. Plz fix that. And I don’t know how to get characters ethier. Thanks for reading my review.
