Enlighten-mint is overpowered
I first got Enlighten-mint the first time it was released, haven't seen an event for it since. But it's AMAZING.
Even at level 1 (I'm not a p2w so I could only get it level 1 before the season ended) I've used it to breeeeeze through the levels.
This would be my strategy:
Plant 2 rows of sun-shrooms (I just skipped to Dark ages, got sun-shroom, and got out, then I went to work on the worlds before)
Throw down an Enlighten-mint and it will INSTANTLY GROW all the sun-shrooms and the sun-shrooms would give you like 125 sun each right before Enlighten-mint expires.
Basically leaves you with 1000+ sun to do whatever you like, then a short while after you get buckets of 75 sun from each sun-shroom and INFINITE POWER
Really, just spam bloomerangs, they're reallly powerful (Same cost as A.K.E.E but hits targets 2 times.). I believe any level can be completed with enough bloomerang spam.
They penetrate shovels, energy shields, and double damage to boot. Just two bloomerangs can kill a buckethead, and even with just two rows of bloomerangs I could beat most big wave beach levels that had surfer zombies.
Plus you can spam spikerocks, melon-pults if you're feeling extra overkill, even lay down QUITE a few tile turnips!
You'll never lose to a generate sun level ever again.
This was why I had trouble with those wild west last stand levels where they spam toaster zombies.
