Bells & Whistles (Asia Version M) is a 1991 vertical-scrolling arcade shoot ’em up by Konami, originally released in Japan as Detana!! TwinBee. In this colorful “cute ’em up”, you pilot the iconic TwinBee ships through vibrant stages to save Planet Meru from an alien invasion. This specific release streamlines the gameplay by mapping both your forward aerial shots and descending ground bombs to a single button, letting you focus purely on dodging enemies and collecting power-ups.
How to Play
The standard arcade controls map easily to your keyboard:
- Movement: Arrow Keys
- Fire (Shot & Bomb): Z or X
- Insert Coin: Right Shift
- Start: Enter
Tips
- Shoot the clouds to reveal bells, then keep shooting them to juggle and change their color. Blue bells increase your speed, silver ones give you a shield, and flashing ones provide helpful options.
- Be careful not to shoot a bell too many times, or it will turn into an angry enemy bee that chases you.
- Focus on bombing the ground enemiesโthey often drop fruit and other bonus items that greatly increase your score.
