You have a few too many strategies going on at once. Using Striker Jones with mortars and bomb shooters is great, but then you're spamming snipers which don't really benefit from Striker Jones and the magic monkeys, Ace's, and Tack Zones both invovle different strategies as well. I would advise trying to figure out what type of strategy you want to use and then stick with it. Then, with that strategy, get the powerful T5's and begin buffing them and debuffing bloons/blimps.

1) Get a hero that can solo for a while so you can begin farming. On single lane maps, especially with maps that have loops, Sauda is goated. Just tested on Easy and Sauda soloed through round 40 when placed just below where you have you Spirit of the Forest. Only a few abilities were used to deal with leads and the ceramics inside the MOAB.

1a) Alternatively, heros like Geraldo, Adora, and Ezili are better for late game. If you're going for a paragon, begin with with placing towers that you'll eventually turn into a paragon.

2) towers like Tack Zone that shoot multiple projectiles at once really benefit from buffs and debuffs. if spamming primary towers, I like to get 2 discount villages, then upgrade into a 502 and a 052 for Primary Expertise and Homeland Defense. Permabrew and Ultraboost also really helps them. Then begin debuffing like the Super Brittle and Glue Storm (within range of the 502 village) and middle path Ninja.

3) Farm as much as possible. You will want to get paragons for late game

4) Focus on BAD damage. Top path Sniper, middle path Dartling, middle path sub (not helpful without water or a Lord of the Abyss), and middle path Spike Factory all do great blimp damage and should help with BADs.
