Hi everyone, after a little pause I'm happy to release the version 1.5 of Reverse Gnop which has huge updates ! 

UPDATES :- New sound when you get the 2nd ball

                         -New controls !

F : fullscreen if it's not / 1000x950 if it's fullscreen
RIGHT & LEFT : move the pad 
WARNING : When you get control with right or left you have to click (right or of left, doesn't matter) on the window of the game to get the control with your mouse back !!

                       -the musique is looping and don't stop each time you restart

FIXS :-Obstacles no longer generate in each other !!

            -the pad is 1.2 time faster

            -the second ball has a lower maxspeed than the first one 

            -Some optimisations
