Street Ball Star is a street basketball game: shooting, dribbling and the showier side of the playground game rather than a full five-on-five simulation.
Shot timing carries most of it — releasing at the right point in the motion is the difference between a swish and a brick.
Release at the right point in the power meter and use an arc rather than a flat shot — a higher arc gives a bigger margin at the rim.
No — it's street basketball focused on shooting and moves rather than full-court team play.
Yes — drag and release. Nothing to install.
