About 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 \ 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

Changes from the free version
・Correspondence to STEAM ranking by improving the function of the production tool
・Fixed the performance of own machine other than wide shot type
・Abolish left and right free scrolling, widen the screen, and remove the off-screen item radar
・Display the position of falling score items
・Display the position of your aircraft on the mini-map
・Changed the counter during true boss battles to "total of boss destruction items (BOSS MEDAL) on each side"
・Changed to not being able to continue after entering the true boss battle (according to that, the no continue bonus has been abolished)
・Changed so that you can practice in practice mode as long as you enter the true boss battle (true boss achievements cannot be unlocked in practice mode)
・Changed 2 types of hidden aircraft that were unlockable to be usable from the beginning.
・Blur effect is used for production (parts related to game play can be turned off)
・Change all BGM
・Compatible with controller vibration function
The latest free version was ver2.4, but I started over from 1 as (verS~)

Epic & challenging Bullet Hell warfare over land & in space, with a variety of weaponry (The black smoke weapon is quite unique). New graphics settings & updates allow one to customize the look & feel in a way that greatly improves upon the original. The soundtrack is excellent! I'd love to see this game updated with further ships & weapons!

Really good, awesome music and gameplay. Nice and short as well. I like the BGM customization too. Last stage does not ♥♥♥♥ around.

great heavy metal soundtrack, several ships to choose, fairly short runs but high speed gameplay. Goes on sale for 60%, so nothing to loose.

great score-focused play, and quite a bit more digestible than the arcade inspirations. can't go wrong with this one, especially if you like fun scoring mechanics.

Ridiculously good value. The music and sound design are top notch, visuals are crisp and clear (giving some Raizing vibes!) and the gameplay is extremely satisfying. For this price you'd have to be a fool not to pick it up, regardless of your skill/experience level.

One of the best score-focused shmups of all time. If you like medal chaining, offensive score bombing, and boss cancels, you'll love Kaikan. The Steam version has a lot of nice QOL updates but also has a pretty different aesthetic from the original doujin version with the new soundtrack, some altered graphics (the new medal sprites look kind of washed out to me) and the removal of viewport panning. I think both versions have their appeal, I say pick this up to support a dev who very much deserves it and try playing both!
