Greater Than One is the eighth level of Doorhaven. It is the first level to introduce Bulk Keys and Bulk Doors.
Description
You're doing well! Since you understand the basics of keys and doors now, let's introduce Bulk Keys and Doors! I think it's also a good time to mention that by hovering the mouse over a key or door, you can see all of its properties, and you can also place Pencilmarks by using [LClick], which will be very useful for keeping notes!
Puzzle Logic
If the bottom-right 2-white door is opened first, there will not be enough orange keys to get the 6 white keys that are needed. As long as the left 2-white door is opened first, the puzzle pretty much solves itself.
Solution
Grab the 2 white keys, open the middle left 2-door, and pick up the orange key and 3 white keys.
Open the bottom-right white 2-door and pick up the 2 orange keys and white key.
Open the top-right orange 3-door and pick up the 4 white keys.
Open the middle-right white 6-door and touch the goal.
