The white square ended up on a dangerous site and it still cannot get out of there, which means that it will have to adapt and survive in Gridstep. Periodically, red squares will appear on the field in different places. If our hero finds himself in one of them, his life path will end. Move it with the arrows, trying not to hit the red one. At the same time, you need to try to catch the green square, which will also constantly change location. It is impossible to foresee where the red figures will appear, a lot depends on luck and quick reaction in Gridstep.
