The game is simulating space where there is a black hole that swallow anything that come nearby , as a player you're playing as a light , there are also some lights and black holes and other objects in the area , the black hole swallows every thing and expands , as light you can escape by collecting lights to push you away from the black hole and avoid taking small warm holes in order to survive , also there is another objects that has an effect on you , try it your self , to win the game you have to survive to amount of time that black hole takes to reach specific size (key portal ) before reaching it there is a red portal and it closed you cannot pass it unless the black hole reaches that specific size and boom it turns blue and you can escape now , the controls is just two clicks on the edges of the screen (right, left) move clockwise and anticlockwise, I assume you play the tutorial to fully understand the game , I hope that the game has a new ideas , also joyful and interesting experience .
