Sometimes the screen has this weird flair around the edges. What does that mean? Also at times I see a black cat. I have found that that's supposed to mean there's some secret area somewhere. Sometimes I find it. At times there's nothing there at all. I'll search the area for good 5 minutes hitting every single thing. Trying to enter openings but I'd there's only six or seven places where I've been able to go into after breaking a door or some rock or some bushes. I have watched other people play who go into secret areas but when I tried to go into the same area the game doesn't let me go in. How am I supposed to know what triggers what or where I can go? I'm so confused about what stuff means in this game.
