Finally completed. (sigh) Simply press "SPACE" to jump. Button below: "Save" to gain save code. "Load" to enter save code. "Mute/Unmute" to mute/unmute. "Change Circle" to change the "circle". There are 8 kinds of (nice) circle. Hope you like it.
Sorry, this might is a copy of a Android/iOS game. I just use the idea of the Android/iOS game and make it to a scratch program. :) There are some bugs such as the line is disconnected to the next line/ the circle is out of the line?! (P.S. The "Warming Up" is for fixing the "disconnecting the next line" bug. Sorry for inconvenient.) (IF YOU LIKE IT, I WILL MAKE "Circle 2") **Save/Load function supported. But Circles are not saved. Sorry...may be a week later I will add this function back.
