I have an explanation on how to dunk ez mode. its not that hard actually. Lets cut to the chase.
Head to practice to learn.
You know to sprint holding the ball right? you press right arrow key with spacebar. While doing that, you see where it says "DANK" which mean dunk lol? When you sprint there, you jump.(let go of sprint when jumping so you dont shoot) In the air, you go quite fast. So hit Down arrow key and spacebar at the same time immediately so that the dunk can be made.
Try this with other playable characters, because believe or not, they all have different places to dunk.
Was this helpful? If not, or you are struggling, probably working on timing your jump in the orange circle(in practice) or time your dunk while in the air. Remember you go fast while dunking, especially the guy with longhair sitting on the floor.
When you got it down, tell me!
