You are playing Quest Buy Rush
Join Star from the animated show, Star vs. the Forces of Evil , races through Quest Buy on a rocket scooter.
It is a platformer game with some elements of a rail shooter, similar to Bit.Trip Runner and Sonic Dash. Gameplay takes place on a 2D plane filled with randomly generated monsters and Quest Buy sloth clerks, and players control Star Butterfly as she moves automatically from left to right on a rocket-powered scooter.
The game’s field of play is split into three lanes: top, middle, and bottom. Players can jump over (or on top of) approaching obstacles by tapping the screen and switch lanes by swiping up or down on the screen. Monsters can be jumped over or shot with power-ups, but sloth clerks cannot be jumped over or shot, and the player must switch to another lane to avoid them.
Coins or crystals are collected as the player plays and used to purchase power-ups, extra lives, and optional alternate costumes. The objective of the game is to get as far as possible and get as high a score as possible before hitting an obstacle and losing. There are also additional objectives that involve collecting a certain number of coins/crystals or jumping over/shooting a certain number of monsters.
