Bloody puddles CHIMP

[-=Venom=-]

Is it even possible to do today ?
Did the sub and dart got silent nerfs ?
No matter what i do , no matter which tutorial i use , which is only one over and over again , with dart on the left and sub on the right , i cannot reach even wave 8 , everything must be so ♥♥♥♥♥♥♥♥ pixel perfect that if ill go past wave 6 by some miracle , the sub will fail because it cant shoot through 2 bloons at once , so i need another 50 tries of wave 6 to reach wave 7 to yet again , fail and start 50 tries all over again.
How much RNG dependant can one chimps be ? That is not how you should make a hard challenge in your game to be 100% rng dependant.

I'll be honest, yea it's kinda precise placement but I got it about 98 times out of 100 attempts I did on that chimps. What helped me was to look at the grass in the left with the placement. That's one thing which isn't rng, the major bs is that there's just small chances to fail almost half the rounds, tho I guess that's not a problem for you if you use some failproof tutorial.
