Pentacolor Pattern is the third bonus level of Doorhaven. It contains several passages of single doors with matching keys in from of them, while a series of double doors blocking the goal force the player to exchange between key colors in a specific order.

Description

Oh dear. Looking at all of these keys and doors arranged in this cool pattern is making me a bit dizzy... But hey, at least most of the doors have matching keys in front of them, so you'll certainly have an easy time opening them. Whether that solves the puzzle or not, I'm less sure of.
