Ok... reach level 7 or 8 (the one after the 4 big jumps gaps), but run out of patience lol. As you said in the community... it HARD. Specially when the target platform is lower than the starting jump point, or viceversa, and you can't make the rewind ball jump highter or lower.
The game is really good, could be great if you tweek that small issues. Congratulations!
