Key Maze puts locked doors between you and the exit, with keys scattered around the maze. Each key opens a specific door, so the route is not the shortest path — it is the order in which you can legally collect and spend. It is a dependency-ordering puzzle wearing a maze costume.
Look at the maze: keys, locked doors and the exit.
Work out which key opens which door.
Collect keys in an order that keeps every later door reachable.
Move through the maze and reach the exit.
Levels add keys, doors and dead ends.
Dependency planning — sequencing actions when later steps depend on earlier ones. It is the same reasoning as planning a build order or working out what has to happen before what.
Map the dependencies before you move. Which door hides which key is the whole puzzle.
Find the door that hides a key you need for another door. That is always the critical step.
Watch for a key behind a door it opens — if you see that, you have misread the colours.
Take the longer route if it collects a key on the way. Shortest path is almost never the answer here.
Yes, each key opens its matching door.
Levels are generated so a valid order always exists, but taking a wrong route can cost you time even when it is still solvable.
No. Maze Runner is navigation speed; this is ordering under dependency.
Start from the exit and work backwards, asking what you need to be holding to get there.
