The Inner World is a humorous point & click adventure with comic graphics. It is set in Asposia, a hollow which resides inside a universe of soil. Air is provided by three wind fountains - but now one after another stops to function and unpleasant wind creatures roam the land.
The player takes the role of Robert, a naive and young musician, who slides into the happenings and eventually has to save the day. During his journey he travels through Asposia; later together with the mysterious thief Laura.
While the game is set in an bizarre world, gameplay is more traditional: Robert moves through the areas, takes items and talks a lot with other characters. The puzzles are mostly solved by using items with other items. The controls are touch optimized, even for systems with mouse controls: clicking on an object brings up a menu with options and items have to be dragged from the inventory into the world. When the player is stuck, there is a help function available which gives (gradually more explicit) hints for specific puzzles. It is also possible to highlight interactive objects.
