Kaikan

Kaikan is a doujin PC SHMUP released in 2013 by Zakichi, who has released several games under the name -kigekiyahonpo-. The game is inspired by Raizing games where medal collection occurs, but with a focus on vacuum effects on medals instead of needing to collect them by touching them like in a Raizing game. The game was created solely within Shooting Game Builder and features royalty free music from various artists to fill in the game's soundtrack.
