I'm glad you enjoyed it, I really tried to make some fun moments when the player realizes they can scale certain things.
Hitting the arrow mid air has definitely been a problem puzzle for a lot of people, even though I think people often do it the harder way (hitting the arrow while big and turning it small, instead of turning a smaller one big) Ill make sure to take a look at it to see if I can make it less demanding yet still the same idea.
