Aiming felt unintuitive which really made having such a small amount of shots punishing. The projectile would go right over the bean, wasting the shot. But it's great that you're learning and were able to produce something to submit in the timeframe. With a little practice, you'll improve exponentially. Keep on Jammin.

Shot going over bean was intentional, after destroying an object you need to move back a little to then destroy the bean under it, and without any aiming help I guess it might be annoying, so maybe not that good of a design choice :)
Having some sort of aiming reticle that shows where a shot might land could probably be helpful, but it is currently beyond me how to implement that.
