With perfect timing, the fun never ends... whee!!!
Runner Coaster, an obstacle-course game, features endless runner elements in a thrilling waterslide environment. The player's primary objective is to help purple, stickman-style people speed down white, bubbly waterslides and gravity-defying, loop-de-loops high in the air. They must speed past deadly obstacles blocking their way while in nothing more than yellow, rubber-ducky, inner tubes.
The player starts with one person and collects more along the way to create a train similar to a rollercoaster. The game uses sections of the slides marked with arrows to increase the speed at which the stick people move in the water. As they slide, the game displays smiling or frowning emoji above their heads to indicate if the player is performing well or not, respectively.
If the player fails to pass an obstacle on any part of a waterslide, such as moving purple wedges, bouncing soccer balls, stuttering fan blades, turnstile barrier bars or button-style, hydraulic smashers, they must restart the entire level. If they succeed, the train reaches the end of the level and each person breaks from the front and splashes happily into a large, circular swimming pool with a pink rim.
