Geometry Dash World
The main character has to go through a rather difficult route using just one jump button. The character is constantly moving and has no way to stop, and on his way there are spikes, walls, pits and other deadly obstacles. You need to have a good reaction and remember all the features of the level, so as not to die in the first few seconds. All musical transitions are perfectly synchronized with the player's actions, so it's easy to adjust to the required passing rhythm here.
