You impersonate a red square, starting its existence in a green starting zone, which moves through a maze of evil blue balls that you must avoid at all costs. You’ll have to collect yellow dots and then land in the safe green zone to move to the next level.

There are 30 levels to beat, and even the first ones will put your skills to the test.

Controls

Here's what each control does:

Use the arrow keys to avoid all the obstacles and finish each level!

Time your movements decisively

Timing and precision are key to surviving a level in the World’s Hardest Game. Ensure you find the most ideal moment to make your move - even a fraction of a second makes all the difference.

Learn the levels well

Unless you’re a speedrunning master, you will be dying repeatedly. That lets you learn the level and see where you’re going wrong. Notice how the obstacles move; the blue balls always travel in the same direction and at the same speed. Use this pattern to plan your tactics for reaching the green square.
