Hello? Hell..o? is a Japanese RPG horror game. All of the events trigger different events.
You play as a boy named Kazuki that is going through strain in a relationship with his girlfriend, Akari. The game takes place in a strange room where you have to accomplish certain things in order to complete all the endings. There are over 30 endings to accomplish (with seven more endings, 5 bad, 1 good, and one "Truth" end), meaning you'll have to play it over and over again to beat them all...with the title screen and room changing almost every time you return.
(*possible spoilers*) Edit
While playing the game the player starts learning more about the relationship between the two characters. It is suspected that the game takes place in two alternate dimensions, one being where Kazuki lives and Akari died, and the other being where Akari lives and Kazuki died. In each dimension the living protagonist is being haunted by their deceased partner. If the player succeeds and reaches the True End the living characters are united.
Endings (spoiler warning) Edit
All of the endings are linked to everything in the room. Anything the player does will trigger a different event. The endings that really matter are in the final scenes with Akari & Kazuki's ghosts.
Akari's Ghost Edit
Bad End: Poor Communicator- This ending is chosen if you choose to scold Akari's ghost. You express to her ghost how you are still alive and how she should put her soul to rest. She then proceeds to kill you.
Happy End: We're Together- This ending is chosen if you choose to hug Akari's ghost. You embrace her spirit telling her that you love her and that you will never leave her. Her deformed ghostly body then starts to resemble the original Akari.
Bad End: Why Must You Run?- This ending is chosen if you choose to check the room and run into Akari while moving around or try and leave the room. Akari will then kill you.
Bad End: Wrong Number- This ending is chosen if you choose to check the room and run over to the phone. A call is then made to Akari expressing how you(Kazuki) are still alive. Ghost Akari kills you while on the phone. The game then picks up in Akari's dimension receiving the phone call.
Kazuki's Ghost- Edit
Bad End: Unringing Phone- If you don't choose to call Akari in Kazuki's dimension you will arrive in Akari's dimension without the phone ringing. At some point as you walk around the room Kazuki's ghost runs in and kills you.
Bad End: Why Must You Refuse?- Same as in Kazuki's dimension, this ending is given if you walk around the room after being approached by Kazuki's ghost and you run into him or try to leave the room. Kazuki will then kill you.
End 28: Another Lover- Labeled as one of the standard endings, this is given when Kazuki's Ghost approaches you and you run towards the fireplace receiving the other Kazuki's help.
True End: Mirrored Lovers- Edit
This ending can only be reached if End 29.... Another Lover is completed while in Akari's dimension. The game travels back to Kazuki's world where he is approached by Akari's ghost. If you choose to "Check The Room" you will hear Akari's scream. Run to the fireplace. Akari will be pulled through the fireplace and be reunited with Kazuki (along with Kazuki's ghost from her world). Akari and Kazuki escape through the door. As expressed in the dialog "The girl whose hand I'm holding now.... Is it the real Akari?" by Kazuki, both of them are in love with each other but realize they are from different worlds and so they may be different than who they expect them to be. As a bonus, the developer shows the ghosts of Akari and Kazuki falling in love as well.
