VIVIT-99

VIVIT-99 is a vertical-scrolling battle royale shoot 'em up created by Shunsatsu sare do? member Ponchi for April Fool's Day. The game's concept is inspired by Tetris 99, though it doesn't feature multiplayer.

The game was only available for one day and was taken down afterwards, but it was later included as a bonus in Banshiryuu Thin Book.
