In the world of black, white and gray, blue villains leap over the red spikes and want to escape from the factory where they are imprisoned. Unfortunately, I got stuck at the second level. There is a place with sharp spikes up and down, so you need to master a very appropriate distance and jumping height to pass. The game has clear instructions. The overall design of the level is very wonderful, and the location of the spike has also been calculated ingeniously. The best part of this game is the sprint mechanism. In addition to simple acceleration, game designers designed sprint bars to limit sprint time. This has changed the overall playing method and tested the players' technology even more.
