Hey, thank for kind words and feedback!
You had some problems at the beginning - are you talking about not knowing how to toss a ball, or was there something else? I want to add a tutorial and it would help a lot if I knew what to focus on. I also intend to remake the whole movement - will simulate friction myself, instead of leaving it to the physics engine, it should make stopping less slippery and walls less sticky.
P.S. Is this Raven on your profile picture? :v
