Thank you!
The pencil SFX is a lucky accident and I never noticed it until you mentioned it! It is the same ground-hit sound, but when a rigid body is hit, I made it subtle.
I had so many plans for the world, some easter eggs etc., but I am no artist and just started learning game dev, so I am happy for what it is now. But I do plan to improve it over the summer. Thanks again for the feedback!
