Yes. We paid attention to the graphics and ignore leave enough time on game design and the gameplay which caused some terrible experience. The design of the random movement is to simulate the unstable gravity on this planets. While almost every player does not like this design and I respect our coder and allow her to design it. But in the next step we will delete this design and try to realize this function in another way. Sorry for some uncomfortable experience during gameplay. Thanks for your comments and I am going to enjoy & rate your game now~
