B-Wings (Famicom)/Gameplay

General

 * In this version, there are only 30 stages, and no enemies will appear on the ground level.
 * At Stage 1,5,9 and every four stages after, player must choose one of the ten common wings and start the stage.
 * Colliding with enemies or bullets will cause your fighter to lose the equipped wings if any. Colliding with obstacles will always kill your fighter immediately.
 * If you die on stages that has no option to select a wing, you start a new life without wings.
 * When your fighter is destroyed, you have about three seconds to continue shooting bullets before returning to a previous point. However, if you manage to defeat a boss before returning, this miss will not count and you can start next stage without wings (unless the next stage has an option to select a wing).

Hidden items
In addition to the hidden wings, the Famicom version has a few more hidden items in most stages.
 * Voltage: Appears in middle of every odd stage.  This item looks like a green icon with "VOL" character.  Collecting this item adds a charge to wing changing, which is used by pressing  when paused.  Beware that, hitting this item before collecting it will turn the item into a useless umbrella.  There is no limit of stocking this item, and each pickup adds one to useable stock.
 * Black Diamond: Appears in middle of every even stage, except Stage 30.  This item looks like a bracked alphabet letter.  Attacking this item will change the letter displayed, and collecting the item will change your wing into the corresponding wing with that letter.
 * Trump Icon: Found under the obstacles in Stage 4, 8, 12 and every four stages after.  This item first appears at a shuffling state, and one shot will put it to stop at one of the four trump icons:
 * 1) Spade: Same as Voltage but with three charges.
 * 2) Heart: Grants an extra live.
 * 3) Diamond: Grants three charges of colliding with obstacles' weakness points without damage.  Players will still lose a fighter when colliding the armored parts.  The fighter will change appearance with this item in effect.
 * 4) Club: Grants three charges of colliding with enemies and bullets without damage.  Also changes the appearance of your fighter.  Another appearance is available if your fighter has both Diamond and Club powerups.
 * Knight Piece: Found under the obstacles in Stage 8, 12, 16 and every four stages after.  This item looks like the Knight piece in the chess.  Grants an extra live, but may be destroyed by shots, which causes this item to become useless umbrella.
 * Comet: Found under the obstacles in Stage 2 ,6, 10, 14, 18, and 22.  This item looks like a star with one wing.  Collecting it will show the word "SKIP" and warp the player to four stages after.  Shots will turn this item into useless umbrella.

Obstacles

Unlike in arcade version, all bosses have a durability meter at their cores and you need to pour in lots of bullets before destroying them.
