Alien Cubes is a fun arcade game in which you have to help alien cubes get through an obstacle course by climbing up on the blocks. To start the game, click on the "Tap To Continue" screen, and then on the arrow in the center. In each level, the cube must reach the finish line. The entire road is dotted with sills. In order for the cube to be able to get over them, you need to build blocks from below in order to climb. Otherwise, the alien will crash into a barrier and die. To do this, simply click on the alien with the mouse as many times as you need to create blocks. Please note that there are tunnels in places, so with a high pyramid you will not get through there.
