Since the last update, there is now a new way to earn stars besides collecting them when you earn points. When you finish a round of the game, you’ll see an offer pop up offering free stars in exchange for watching an advertisement video. Tap that and let the video play out in its entirety. Once it is done, you will earn 30 stars. Repeat until you have enough stars to buy the new skins that you want.
Reverse mode is a new mode that has you going down instead of up, but, like challenge mode, this is also level-based. You still bounce up when you hit the screen, but it now requires a whole new type of timing to get through the circles. When holding in place, though, the timing is the same. Bounce before you hit the bottom of the obstacle (or the top of the obstacle if you are above it), then fall through when you can.
Race mode is the same thing is challenge mode, but with one exception. You have to race against a ghost circle, which will, after the first play through, be your own ghost circle, but during your first time playing, it will be a preloaded one. If you don’t beat the ghost, you lose, even if you cross the finish line.
Cave mode is exactly the same as challenge mode but with different level designs, and but for the fact that you can see stuff that’s very close to your dot – about a one centimeter radius on an iPhone 6 Plus. Take it a little bit slower in this mode so that you don’t go barreling into the next obstacle before you can even see it.
Color Fly mode is thus far the most original mode in the entire game. The levels are sideways instead of up and down here, and you fly forward and tap to bounce, like in Flappy Bird. The obstacles are the same shape, and flying through the front and back takes a bit more strategy especially when they are moving while you are inside them.
Color Swap mode is just like Challenge, except that the colors will change randomly, rather than in between obstacles. Watch out for the screen to flash a little bit three times. Once it flashes three times, the next thing it will do will be to change the color of the ball. It changes every 10 seconds or so.
