Three Choices is the sixth level of Doorhaven. It has three different paths to the goal, as well as a few consecutive doors and keys. Despite the layout difference, it essentially involves the same logic as the previous level, Tunnels.
Description
Oh my! There are three paths to the goal now! That's like, there times as many ways you could mess things up! So...Which way is the correct one?
Puzzle Logic
Based on the "forced moves" logic of the previous puzzle, the player should first clear out all of the orange doors with orange keys behind them. This leaves just the middle path to spend the orange key afterwards, giving a cyan key in return.
The cyan door in the middle has another cyan key behind it, making this a forced move. It also gives the player an orange key.
After this, the bottom cyan door is the only viable option, giving the player a second orange key.
The only place to spend the 2 orange keys is at the top row, giving one cyan key.
The cyan key can then be used at the bottom to get to the goal.
Solution
Pick up the orange key.
Open the middle orange door, pick up the cyan key, open the middle cyan door next to it, then pick up the orange and cyan keys.
Open all bottom doors except the last, picking up the orange key.
Open the three top orange doors and pick up the cyan key.
Open the bottom cyan door.
Touch the goal.
