The game "Perfect Time" is an interesting arcade game for the speed of reaction, in which you need to catch the right moment to pass an object through a gap among obstacles. Click "Play" at the bottom and go to the first level in the list. Click on the jar to drop a ball out of it. When he rolls over the platform, the level will be completed. Then there will be barriers. You will have to drop the ball at the right time so that it rolls despite the plying block blocking the path. Then you need to get into the hole of the circle flying like a pendulum. Next, a rotating fence will appear on the arena without one beam in the middle. Click on the suspended beam to make it fly into the gap.
