KAIKAN

A vertically scrolling shooter where you mow down enemies that stand in your way.
Aim for a high score with items that appear by destroying enemies and bonus items that can be obtained by using bombs.

game description

Destroying enemies releases bonus items.
Collecting bonus items will increase the item rank and increase the item's score.
If you miss it, your rank will go down one level [PENALTY] and your rank will not fluctuate up or down until you get the number according to your rank.
Bonus items can be attracted to your aircraft by releasing the shot button, and if you press the shot button while being attracted, they will fall again.

This item also increases the bomb gauge (purple), and when the bomb gauge is full, bombs will be stocked. (Only one stock)
If you are hit with bombs stocked, your aircraft will be protected by an auto barrier, but you will lose your bomb stock.

When you fire a bomb, enemy bullets on the screen will be converted into bomb bonus items, and enemies hit by the bomb will release bomb bonus items.
This item has a higher score than normal items and also increases the counter on the right side, but does not increase the bomb gauge.

The counter acts as a timer in boss battles and affects the score of bosses and boss parts.
Items used when destroying a boss will restore the bomb gauge and will be counted as BOSSMEDAL, which will be used as a counter for the final boss battle.


You can choose from 6 types of aircraft, and the characteristics and behavior of weapons change when moving at low speed.
typeA: Napalm that explodes when it hits an enemy
typeB: Wide shot that can attack in a wide range
typeC: Homing that tracks the enemy
typeD: Fire that attacks to cover the screen
typeE: Blast that emits high power
typeF: A ball that rotates around itself and erases enemy bullets
