It's almost working, but I actually need the sprite moving right to change it's size to 50,50 not the one that's moving left.
And why does the sprite in the top left corner, This sprite:
Why does it have its size changed to 50,50? It should stay the same since it doesn't overlap a sprite with a powerup.
Sorry about all the questions guys!
It's just that getting the same object type overlap to work is extremely confusing for me since it doesn't work like a normal overlap between two different object types.
