It does not exhibit projectile motion and follows a straight path down the ramp.

While the ball is in contact with the ramp, normal and frictional forces act on it in addition to gravity, so it is not in free-fall (not a projectile). Its motion is constrained to the straight incline (assuming a straight ramp). (If it leaves the ramp and becomes airborne, then it would follow a parabolic projectile trajectory.)
