The controls in the game are as simple as possible, but the game itself will be quite stressful. First, the character will fall down, click on the left mouse button or on the device screen to make the character jump, using the jump, get to the finish line at the end of the level, passing various obstacles. You can touch the ground and the ceiling, but you need to dodge obstacles. If you hit an obstacle, then the level will start over. There are portals in the game that change the rules of the game: 1) the yellow portal changes gravity so that the character will not fall down, but up, and the jump will not be up, but down. 2) The blue portal changes gravity to normal so that the character will fall down, the jump will go up. In the game, you can select a skin in the main menu of the game, in the button with the UFO icon, select the skin you like, and it will appear at the game. To complete the level, you need to stay alive until you touch the finish line.
