this puzzle becomes fairly easy if you abide by the rule of always picking low-hanging fruit. if any apple appears to be a little out of reach, move on and grab another one.
you may expect box 1 to be the first break-in. it isn't !
the middle section of the solve may seem very hard, but extensive goodliffing will get you past that, as there's a ton of quadruples.

I really must have missed something obvious because this took me quite a bit longer than usual for a 2*. Either way, very fun one. Thanks for sharing.

I agree, I published this as 3* but it was voted to 2. Thanks for playing!
