I am an average player on Jungle cruise. What I have learn to do it memorize as close as I can the first round and the sweet spots.
This getting over 15,000 the frist round close to 16,000
The second round I click the area as soon as there is smoke. Keeping my mouse pointer to the middle. More chance of getting a some flawless.
Last round I pray just to click them as it goes fast. Even missing quite a few I still managed to get 48,000.
Key tip do not crash into anything first round if you do chances are you will not have enough gas (better to start over)
Never put on gas.
Float in same save spot and a lot of times there is a pause and it looks like all the animals are gone but they start to pop up again.
Check how much film you have if a film is blocked in and you have plenty leave it there is a rolls in another room easier to get.
Do not miss any gas cans.
And relax stress causes you to stiffen up and then you can not move as well take if from me breath deep and forget you need 45,000 will just make it horrible.
