PUZZLE 177 Level Up 2

A group of monsters has appeared!
Defeat all of the monsters and level up all three of the heroes to level five.
They each need a different number of experience points to level up: blue needs tne, yellow needs fifteen, and red needs twenty.
Slide the heroes the move them on top of the enemy to attack.
It's also possible to cancel a move by touching the enemy under attack.
Let the battle commence!

Hint 1

When all of the monsters are defeated, the heroes will have gained 180 experience points between them.
Figure out who needs to attack which monsters so that none of those points go to waste.

Hint 2

To attain level five, blue needs 40 points, yellow needs 60 points, and red needs 80 points.
So that none of the points are wasted, be sure to figure out a combination that results in the units figure being zero.

Hint 3

Let's take one possible combination.
Red needs 80 experience points.
This is quite a high number, so why not go for the monsters with the highest number of points?
You could start with red attacking the 27 and 28 pointers.

Super Hint

Continuing on from hint three...
Blue needs 40 experience points.
Defeating the monsters worth 3, 18 and 19 points would result in a score of 40, so have the blue hero attack them.
Then you just need to mop up the remaining monsters' points to get everyone to the right level.
