Catch the butterflies before the reach the top from the screen. To catch the butterfly, you need to find at least three of the same kind connected to each other. Just touch them to collect them. You have a limited amount of time to earn the points required to reach the next level. The stars on the right side show the progress you made to the next level. The more butterflies of the same kind you catch with one click the more points you will get and the sooner you will get to the next level and earn time bonus points. The ‘question mark’ is a joker that can be used as any butterfly, the dog footprint will clear the butterflies from the screen.
