Detuned World+ was a Paper Game by Detuned Paper as a part of the Detuned World series. It was originally released as Detuned World, but was later updated to include some small patches and a competitive multiplayer mode and a + was added to its namesake to indicate that it was the definitive final version of the game.
Gameplay[]

The Forest.
At the beginning of the game, the player is asked to choose between three unique class types that determine their starting stats, which can increase as the player gains experience through encounters over the course of the game.
The player then has to explore a large region, battling and sometimes capturing creatures and using them to form a team to defeat enemies - similar to Pokemon. Each creature in the game has different ADS stats (Attack, Defense, Speed) that determine the outcome of any given battle. The player encounters these creatures when wandering into their corresponding regions, each of which has a predetermined danger level based on the difficulty of the screen.
Each screen consists of a few different elements, these being the environment artwork, collectible items, npc interactions, and enemy encounters. As the player progresses through the game, these screens scale with their own growth. The remainder of the screens are menu screens, which include the world map, the item screen, the skills screen, and the radio transmission screen.
Story[]

The player is introduced to the world abruptly and is told that they have fallen through a portal leading to this unusual landscape. Over the course of the game, it is slowly revealed through radio transmissions and NPC interactions that the Detuned World serves as a place of experimentation for a certain government organization. It can be speculated that all of the people found in the Detuned World were either placed there by this organization or appeared by way of a freak accident.
According to Detuned Paper, Detuned World only displays a small section of the wider environment that is available to explore in this foreign land. The rest of the Detuned World is said to be revealed in future games in the franchise.
