How to play Kiss the Rat

[DigiAkuma]

So one of the tasks is Kiss the Rat & I'm lost at what I do. From what it looks like, I hit to left or right, but every time I "hit" I seem to miss & every attempt I end up with 0 points. I must ask, What's the trick to the game to at least connect with the hits?

basically pressing the right button for the right color
but also timing
my catch is to press when it's already in the middle of between me and the enemy, because the knocking animation is rather slow

but its all comes to practice and getting used to connecting the animation and our reaction
