Boulders and Bombs is a video game for Atari 8-bit computers published on cartridge by CBS Software in 1983.

Bird-like creatures, flying in the upper portion of the screen, launch projectiles into the dirt to thwart the player.

When controlling the spelunker, moving the joystick in a circle drops a bomb which removes dirt, rods, and fungus.

[3] The probe birds can be killed if an exploding bomb hits the fungus injector before the injection process is complete.

In a 2 out of 4 joystick review for Electronic Fun with Computers & Games, Paul Backer complained of the difficulty in planting bombs with a circular joystick motion and also pointed out that a secondary player can easily finish off a spelunker by planting fungus directly in front of it.
