Athletics - World Championship is a similar game to the classic Track and Field which challenges you to participate in a ton of Olympic game trials. You can run 100 meters flat, throw the javelin, pole vault, throw the disc, participate in hurdle races, etc.
In total, Athletics - World Championship includes more than a dozen different trials, each one has its own gameplay. In Track and Field, you normally had to click on the buttons as fast as you could in order to run more. Luckily, you'll need accuracy instead of speed this time. Basically, you have to click on the screen when the power/speed bar tells you to.
As always, there are some trials that are easier than others. For the speed and resistance trials, the only thing you have to do is to keep the heartbeat pace in order to run. However, for the javelin or hammer throws, you have to control the movement speed as well as the strength of the throw.
Athletics - World Championship is a simple but fun sports game that offers a ton of variety. Also, its pixelated visuals are really charming.
