Stinger

Moero TwinBee: Cinnamon-hakase wo Sukue!, known as Stinger in the American version is a vertical/side-scrolling shoot-'em-up game released by Konami for the Nintendo Entertainment System in 1987. It is the second game in the TwinBee series, which was originally released in Japan for the Family Computer Disk System expansion in 1986 and later re-released as a last Konami game for the standard Famicom cartridge in 1993. Moero! TwinBee for the Disk System was the first of two TwinBee sequels released for the Famicom, followed by TwinBee 3 in 1989, which was released only in Japan. A few changes were made to the NES version, Stinger, from its Famicom counterpart.

According to the American version's back-story, a race of alien beings from the distant Planet Attackon located at the Ergo Galaxy have kidnapped Professor Einstein J. Cinnamon, a brilliant scientist who has invented bio-nuclear sweetener. The Attackons want to use the Professor's sweetener formula to turn the Earth into a giant ball of cotton-candy. The player takes the role of a pilot controlling the 'Stinger', a spacecraft built by Dr. Cinnamon, in order to rescue the scientist.

Much like the original TwinBee, Stinger can be played by up to two players simultaneously (three players in the Japanese versions). Unlike the original TwinBee, which only featured vertical-scrolling stages, Stinger adds side-scrolling stages to the mix as well. There are seven stages in the game. Stage 1, 3, and 7 are side-scrolling stages, while the rest are vertical-scrolling stages. The controls remain the same between the two styles of gameplay, with the only difference being that in the side-scrolling segments, the A button shoots hearts over the ship instead of dropping bombs into the ground like the vertical-scrolling segments, which helps the player keep the power-up bells afloat in the side-scrolling stages.

The player's primary power-up items are once again bells that uncovered by shooting floating clouds throughout the stages. There are six types of bells in this installment: the regular yellow bells give the player bonus points as usual, the blue bells increases the ship's speed; the white bell upgrades the player's gun into a twin cannon; the pink bell gives the player a laser beam cannon; the flashing pink/white bell gives the player's ship mirror options for added firepower; and the flashing blue/white bell will surround the player's ship with a barrier for extra protection from enemy fire. Some power-ups are mutually exclusive, such as the white and pink bells. Other power-ups can be obtained by destroying ground enemies such as a moon item and star item which gives the player's ship a three-way shot and a five-way shot respectively. If two players are playing the game, they can align their ship together to turn their gun into a ripple laser.
