The hit detection is bad sometimes i would get hit even if i did not touch anything. why make it blink after i get hit if i am not invincible during the blinking period just makes the experience hard, and why have a turbo boost at the star if using it mean you can also get hit? not using it makes more sense because then i at least have a chance of dodging. radar does not work makes the money i put in just a waste, i tried re starting the game many times and fully upgraded the radar but did not work. and the objects are very hard to avoid because i can't see i coming.
