・Eris has 3 points of HP, and each time her HP decreases, her armor is destroyed: armor, half-naked, and fully naked.
If you die, you can recover immediately on the spot.
(You can also recover at the place where you moved to.)・Attacks are powered up with items available during the stage.
No detailed manipulation is required. When the attack button is pressed, the item is activated at the same time as the attack.
(The item is activated only when the attack button is pressed with no directional key input.)
("Fireball" and "Bom" are also activated by crouching attacks.)・Stepping on the "H button" during a stage will "disable" all female mob enemies.
(Does not work on mid-boss enemies and non-female enemies)・As you clear the stages, sex scenes will open up.
You can enjoy various sex scenes, including maniac scenes.
Sex scenes are fully voiced and fully animated.
(All voices are Japanese)・There are several unique monsters in the game.
You can choose to "continue" indefinitely, so the game is not difficult.
