Pre-flop: ($0.07) is CO and dealt
UTG calls $0.05, UTG+1 calls $0.05, MP calls $0.05, MP+1 folds, CO raises to $0.23, BTN calls $0.23, 2 folds, UTG calls $0.18, UTG+1 calls $0.18, MP folds

Flop: ($1.04) (4 players)
UTG checks, UTG+1 checks, CO bets $0.75, 3 folds, CO returned $0.75

So are paired boards what we want to see with KK here?
In review i'd say bet less on flop. How much though? Enough to keep 55-JJ still playing or what? I'm looking to get 1 -2 callers max.

Help appreciated.

raise to 35c-40c pre

I usually use the 3xBB +1x BB per caller rule. Obviously I forgot that in this case
You reckon a bit more is better though?

As played you bet the flop fine. 75 cents is a perfect amount with that pot size.
