I can't answer with certainty. So I want to help you as much as I can.
I think if you want to open All Gallery, you have to die from every monster in each stage, whether it's normal enemy or a boss, and you collect 9 golden cards to open stage from version 2.00.and I think there are some ending games that need to be finished. but I don't know if it's true or not. I did not do it because I was too tired

, this game is very good from the H-game I've played

.. that's all I know
oh yeah, you just use Cheat "calluna", it will help you, shots with your mouse. Have fun
