Since this game consists of some back-tracking (levels end with multiple doors sometimes, one easy and one hard to reach) I wonder how you manage to do this.
What systems do you use to do this?
As you know, in order to get all the coins, you have to revisit earlier levels and take the other door to get to different parts of the game.
How do you keep track of what doors you've taken? Have you for instance always done the hard door, or perhaps always done the easiest door?
I'm with PONTO. Often times the harder to get to door will loop back to exactly the same place as the easier door, only there will be a coin somewhere along the way. At least such is the case with area 2.
Seldom is it the case where a coin can only be got via the easier route.
Edit: nvm. I see what you mean now.
