TwinBee (Bubble System)

Twin Bee is an overhead scrolling game starring a pair of bee-shaped robots, Twinbee (the blue one) and his female counterpart Winbee (the pink one), Twin Bee is part of what are called 'cute 'em ups', a slang for shoot-em-up games that feature cute characters, animals and other funny looking creatures, among other whimsical themes and brightly colored landscapes. It's a fun game to play with at least 6 stages that repeat themselves with increased difficulty as you go along.

Power-ups and extra points can be found in special bells hidden in some enemies that, when shot a certain number of times, will change color and then, when touched by the player, will provide a powerup, such as extra speed.
