Bullet rain is denser and its bullets are no longer stopped by anything
Interval dropped from 1.0s +- 0.6 to 0.4s +- 0.25 (about 2.5 bullets per second instead of 1), which measured 13 drops in 6 seconds versus 6 before. bullet.gd gained stop_on_obstacle (default false): the probe raycast is disabled, so rain bullets fall straight through terrain and ropes and are only recycled by their lifetime or by dropping past despawn_y. Verified a bullet falling from y=190 goes through the floor at y=225 and despawns at y=340. Also picks up the editor changes: the rope tiles were removed from level 3 and a few nodes gained unique ids.
