Level 60: 14 moves (unable to find 13), level 62: no solution, level 64: 14 moves (unable to find 13), level 65: 14 moves (unable to find 13). This is the point at which further play ceases to be interesting and becomes annoying. Please provide some help/tips.
I am personally rather against giving away solutions. The whole point is to solve the thing yourself. And as a hacker yourself you can probably write a solver if you really get frustrated and can't move forward. And as my previous comment suggest - you can easily reduce level 62 to a previous 2-ball level which you have solved apparently.
Could you provide some additional hints/tips/solutions for level 60 and level 62 ?
BTW: How many levels are implemented in total ? More than 200 ? If so, then such a difficulty at level 60 is little to high, IMHO (of course, when it comes to finding the optimal solution).
