Thank you for playing.
I really dropped the ball on conveying how to play clearly. Funny you mention being able to view when not aiming. This was a feature. But collisions only calculate on screen so the ball would clip through the obstacles. I only noticed on the last day of the jam while I was adding the arcs to the ball so it looks 3d. I'll address this after the jam if possible.
Glad you have fun regardless.
The hard mode turns off the map completely and the ability to control the direction or power, if that helps at all.
