I love this idea, and think it could make for a very fun physics puzzle game, but currently held back by subpar physics, causing the bar to go through the ball when moving to quick. This necessitates careful movement, but that's very difficult to do with the current setup. I'd love to see some extra player feedback and/or reset button to aid in careful lifting and other manoeuvres. But since a game jam is for presenting an idea and its +s and -s, I'd say you well succeeded.
