Investigator S: Reverse Quantum Curse

Investigator S: Reverse Quantum Curse, 3DS version known as Investigator S 3D: Reverse Quantum Curse (探偵小：逆量子 Detective Esu: Reverse Quantum), is a mystery, 2.5D platformer for the Nintendo 3DS and PC through Steam. It is being developed by X-Scissor, as the first game in the Investigator S series. It takes place in Victorian England, where S and other members of The Agency struggle to protect the nation from the XGen Agency. They must solve several mysteries in order to protect each other.

Plot
The game follows S, a former orphan, and Daka, a child with abusive parents, as they become detectives travel throughout Victorian England, solving mysteries and defeating crime.

In Reverse Quantum Curse, the girls are offered jobs from The Agency, an organization from the future. After accepting, the two find themselves battling with the forces of XGen.

One day, an attack is launched on the base of The Agency. Kira claims that "this is the beginning of the end for the English". Boss A. goes to battle with Kira, but he is defeated quickly by Ranao. The girls go into a fight with the powerful man and defeat him.

Kira flees from The Agency momentarily. The girls head back to their normal jobs at their HQ. Until, one day, Boss A. calls the two in to talk to him. He tells that the two came from the future to stop Kira from taking over England, and he asks for the girls' assistance.

The girls accept their mission and head to the XGen headquarters. They encounter many mysteries throughout the labyrinth, until they make it to the end of the dungeon and must battle with Kirana. After defeating her, they approach Kira.

S is sent to the future by the powers of Kira. In the year 3005, S meets the new Agency, and tells her story. After obtaining a Cross Stopwatch, S is able to travel back to her time. She discovers that the entire Agency has been taken over by Kira.

While S is in the future, Daka is forced to remember horrible memories of her past when she is taken hostage by Kira, after the Agency is infiltrated by the villain and most members are defeated. Daka grabs on to her little remaining hope, when S appears after coming from the future.

After realizing that Daka has been taken hostage, S defeats Kira in battle. Once she is defeated, it is revealed to the girls that, through the destiny of time travel, all of those born in the future after Kira has taken over will be erased from existence.

All members of the Agency who came from the future disappear at this point, leaving the girls depressed. They head back to their homes, but it is later revealed that the Agency's purpose is changed, and S becomes new leader of the Agency, three years later in Violet War.

Gameplay
As Reverse Quantum Curse is a 2D game, the player may only move left and right. Occasionally, in places such as The Agency and London Town Square, the area is three-dimensional, and you may go in any direction. The touch screen (or cursor) is used a lot in the game to uncover hidden objects, select items, and talk to NPCs. You may also press A to select objects.

The player has a bar of health at the top of the screen. It defaults to having three sections. Each time you are hurt, a section is erased. You may gain more of these sections through Health Upgrades. These can be obtained by solving mysteries.

Similar to in many RPGs, you gain Experience Points after defeating enemies and solving mysteries. Every time you level up, you are allowed to solve higher-level mysteries. Unlike in RPGs, your health and attack do not raise after you level up. You cannot progress in the game unless you level up often, however.

The player always plays as S in the game, and Daka is usually walking around with you. You may attack through kicking and punching, although that is not used often. Jumping to reach higher objects or locations is used a lot throughout the game. Daka can occasionally pick up S to help her to jump higher. You may also press B to run faster through stages. If you press B and Y together, S and Daka will hold hands and run faster than before.
