The char­ac­ter is con­trolled by click­ing on the place on the screen where the play­er wants to move. The char­ac­ter starts to accel­er­ate in that direc­tion until it reach­es a max­i­mum speed and then starts to stop, this makes that for each pulse the char­ac­ter moves a pre­dictable distance.

Dur­ing the game there are con­cen­tric rings that are gen­er­at­ed, each one with twice the scale of the pre­vi­ous one, there are dif­fer­ent types of rings that have one or more out­puts. While a ring is active it will shrink in size until it becomes tiny. The char­ac­ter must move to escape through the open­ings because, if touched by a ring, the char­ac­ter dies.

This is the first game to which I imple­ment­ed a trans­la­tion sys­tem which has a record of each text that appears on the screen and arrays con­tain­ing the trans­la­tions for each one, by press­ing the lan­guage change but­ton we go to the next lan­guage of the sys­tem and the sys­tem is respon­si­ble for updat­ing each of the texts on the screen.

The game is set up in two scenes, the first scene is the ini­tial scene of the main menu in which you can also see the cred­its screen. By press­ing the "Play" but­ton we switch to the game scene. Since in the game scene we have on-screen texts, it was nec­es­sary to think of a sys­tem to trans­fer data between scenes in order to assign the text in the appro­pri­ate language.

In the Android and Win­dows ver­sions the sun sprite that appears in the back­ground of the game scene changes size depend­ing on the ampli­tude of the music, this is done by read­ing a chunk of the bytes from the audio clip and aver­ag­ing them to get a val­ue that will then be relat­ed to the scale of the sprite. It is not pos­si­ble to do this in WebGL because one of the func­tions that allows us to ana­lyze the audio clip can­not be used in WebGL. An alter­na­tive could be to pre-cal­cu­late these val­ues for each song and to have these data orga­nized in lists to be applied to the sprite scale.

In this game, data is saved using Play­er­Prefs to remem­ber what the max­i­mum score was and update it if it is exceeded.
