There are three video game genre that I like, Fighting, J-RPG, and Danmaku.
Danmaku(manic shooter, bullet hell) are a sub-genre of shoot 'em up games in which the entire screen is completely filled up with enemy bullets. These game originated in the early 90s as an alternate to side scrolling shooter games. Most of these game are made by the Japanese company, CAVE. When I play these games I feel like I'm in a euphoric state and my body has chills(of the good kind) and my mind is focused until I beat the game. Below I have some videos of awesome danmaku games.
