Tengami is a third-person adventure game set inside a Japanese pop-up book. The visual design resembles a paper world where the player can turn or fold pieces of the scenery. This is not only used for aesthetic purposes, it is also the main mechanic to solve environment based puzzles. The player controls the folding process through swiping or mouse movement and sometimes it is needed to find clues between the folds. In other segments it is used to construct platforms so the character can find a path.
The game is split up in three segments where a male character needs to be guided through an environment to locate three flowers. These bring back to life a Japanese maple tree. There are no items to pick up or other characters to talk to. The character can be moved freely through the environment and can interact with certain items. The puzzles have a hint function where a clue is provided about what to do next.
