In the enchanted forest of Veridia, there is a mystical clearing where spatial dimensions function differently from the known physics of the outside world. In this clearing, there are three distinctive objects: a transparent, unbreakable Crystal Cube that always reflects the true image of anything within a 10-foot radius, a Mask of Invisibility that can make the wearer completely invisible to the naked eye, and an Ever-Shifting Maze that reconfigures its layout at the end of every hour. Three friends, Keiji, Amara, and Dinesh, decide to play a game within the clearing. Keiji, wearing the Mask of Invisibility, enters the maze to hide. Amara positions herself outside the maze, holding a compass that always points towards Keiji, helping her track his movement without seeing him. Dinesh stands by the Crystal Cube, which is located just outside the entrance of the maze.

The game's objective is for Amara to instruct Dinesh to enter the maze and find Keiji based on the direction indicated by her compass. However, there's a twist: the only form of communication allowed between Amara and Dinesh is through a series of pre-agreed hand signals that they established earlier. Furthermore, once Dinesh enters the maze, the compass's pointer stops functioning, and he must rely solely on the hand signals provided by Amara before entering the maze and his memory. 

Just as Dinesh is about to enter the maze, Keiji finds a central chamber within, where space behaves even more peculiarly: time flows backward, making any event within this chamber appear in reverse to an external observer. Keiji decides to stay in this chamber, unknowingly to Amara and Dinesh.

Given these conditions, what will Amara see on her compass, how should she signal Dinesh, what will Dinesh see once he enters the maze, and what will happen if Dinesh manages to reach the central chamber where Keiji is hiding?
Starting with Amara's perspective, as long as Keiji is moving within the maze (but outside the central chamber), the compass will accurately display his position relative to Amara's location. Once Keiji enters the central chamber, where time flows backward, the compass may behave erratically because its magical properties did not account for reverse-time conditions. If the compass is only designed to work in standard temporal flows, it could either stop working or point in the direction Keiji was before he entered the chamber.

When it comes to signaling Dinesh, Amara faces a challenge. If her compass behaves erratically or stops upon Keiji entering the central chamber, her last reference will be the last known direction she could track before it stopped. She needs to give Dinesh hand signals representing this direction quickly before Keiji moves too far into the chamber, making the information outdated.

As Dinesh receives the signals and enters the maze, he has to rely completely on the pre-enter-maze instructions given by Amara's hand signals. He does not have the assistance of the compass inside the maze. Assuming he follows the instructions based on Amara's last signaled direction, he starts navigating the Ever-Shifting Maze relying on his memory and spatial reasoning to move toward the central chamber. Considering the maze changes layout every hour, this is a complex task.

If Dinesh somehow manages to reach the central chamber where Keiji is hiding, the backward flow of time therein poses an interesting effect. To Dinesh, Keiji might look like he is walking backward or performing any other actions in reverse. This reverse temporal flow would also affect Dinesh's perception of his own actions; for example, he might see the results of his actions (like opening a door) before he perceives himself performing the action (reaching for the door handle).

The ultimate result if Dinesh does manage to reach Keiji in the central chamber is that he would need to deduce from Keiji's reversed behaviors that he is indeed in the extraordinary space where time flows backward. Without this realization, Dinesh might become disoriented by the reversal of causality, making it difficult to "capture" Keiji as intended in the game. If he does understand the situation, he would need to extrapolate from the reverse actions to pinpoint Keiji's exact, current (in the sense of backward time) position in the chamber.
