I didn't even think about it as a 'shadow' :-D
The idea was to aim with the circle for the next target while the animation of the pencil is playing -for purely aesthetic reasons.
Always knew balancing in games was hard to do, but never realised just how hard it is. Even with something small like this.
Thank you for taking the time to play our game and giving us valuable feedback!
We'll strife to improve on our design and overall gameplay (:
