Psyvariar Delta

Psyvariar Delta combines both versions of Psyvariar with new content, featuring the game's trademark systems: buzzing and rolling. Buzzing rewards the player for grazing the edge of bullets, encouraging risky play styles. The player receives points as well as experience points, which helps their ship rank up; ranking up boosts the ship's power and grants access to later levels. When the ship ranks up, it also gets a special effect, such as temporary invincibility. Buzz combos build up over the course of a level, but reset to 0 when hit by a bullet. Rolling allows the player to perform a barrel roll by rapidly tapping the joystick back and forth; while rolling, the player's ship moves at a different speed from usual and the shot is focused into a tighter pattern.

The three main game variations are:

The game also includes practice mode, which lets players try any stage with specified lives, bombs, and experience. A replay mode allows players to watch replays of their previous games.
