Bugatron is a Galaga-styled shoot ’em up game where the player must shoot
down armies of insects. The enemies typically fly onto the screen in spirals,
and tend to pirouette all over the screen during the gameplay; depending on
the level they might shoot at the player’s ship or not. Some levels also
contain unique gameplay elements, for example the enemies can only be
destroyed by pushing them off their flight path into an obstacle, or the
player must maneouver through a narrow path in one piece. Destroying the
enemies occasionally causes pick-ups to appear, with both positive (new
weapons, extra life, faster ship, larger enemies) and negative (slowdown,
slower weapon, less controllable ship, smaller enemies) effects.
