Mind that this is about a possible bug in game design on 01/5/2023, so by the time you read this, the bug might have been fixed and this guide might not be useful anymore.

In the level in the Coffee Shop (picture) where we have to get a key, it is possible to take the first key and skip almost all of the puzzle.

Just link panels in order to take the key on this one


instead of the one on that panel


As soon as you pass pass the exit door with a key, the game let you keep it, so you can still return to try to solve the puzzle later.

We can also use that key to unlock the room with a locked door and a key just behind it, back down the sewers.

In levels, the game doesn't care what item we get as long as we get one of the required kind.
