you click the up arrow, the dot will go up, if you release, it will go down, you start at level0, level0 is a practice, start in level1, the gravity is bigger and you can bounce higher, if you loose, press the green flag 2 times to restart! and each level you will jump lower and lower, can you go to level10 or higher! level0----------keep going level1-2----------good level3-4----------great level5-6----------sick! level7-9----------SSS level10+----------XLSSS
Thanks @pencilmanpro-justin for the idea!
