It takes very minimal effort to understand the controls, since all one has to do is tap the screen to jump, and the timing has to be right. A player does not die if the button is pressed late, rather than pressing the button at the exact time. The system implemented in the game is a very sensitive one and so requires a lot of effort and fast reactions. The sounds in the game are much more than just background music because each sound creates a corresponding note, rhythm, shape change, or event in the background. This makes players feel much deeper in the game because they are able to understand and predict the rhythm of the game and the challenges that come with it.
The increase of each difficulty correlates with levels. As players start, the levels are simple enough to help new players familiarize themselves with the game’s controls and aspects. Increments of difficulty are relentless; skillful players are required to have good reflexes and coordination to pass the levels quickly. The combination of unexpected portals and deadly traps makes the player sweat until they pass the level. Players will be forced to try multiple times until they are accustomed to the level’s layout.
