It would be amazing if I could decide which monsters I want to attack (in case they are not aggro) Otherwise maps with a few non-aggro but really strong enemies become unplayable until a really high level.
The trick is to enable Gold Mode. Every dot gives 25 points when activated. To activate it let the first rainbow mode pass without killing any dots, collect dots until you reach 2nd rainbow mode. Kill ~4 or 5 to get some space in the middle and then collect again until you reach your 3rd rainbow mode. Now you'll have ~20 dots on the field and can just kill them all off to get rainbow mode.
