Shiroi Danmakukun is a danmaku shmup trainer by Japanese developer Shinh. It's in Japanese, but there is an option to have English "subtitles".

The gameplay is very basic, all you have to do is dodge the incoming bullet patterns. And last as much time as you can, the amount of time you survive translates as you score. The bullets are too fast for my personal taste, and gives me no time to see the patterns. Which are, in fact quite the sight. My best score is 29 seconds. I suck, hard.

The game is similar to BulletGBA. If you choose the first two options in the menu (Normal or Simple) they appear at random and constantly change (the score I said before was in the Normal mode). But you can choose the 3rd or 4th option, you can choose which pattern you want to use. Including from games by ABA(Noiz2sa) and Zun(Touhou).

The control scheme is not complicated, arrow keys to move, Z to select in the menus and X to cancel. Z also slows down you speed while dodging bullets.

The first thing you may want to do, if you can't speak Japanese, is go to the 5th option in the main menu. And from there turn the English option on.

The game lags a bit while choosing options in the menus, but thankfully not in the gameplay. One problem I do see is that som bullets are red, like yourselft, and can make things a bit confusing.

The game is available for Windows, MacOS and Linux. To download go to the ダウンロード heading.
