A small guide for people (or rather, how to open scenes and survive).
1) To open a girl in the gallery, you need to have 80-100% lust (purple bar). Just try not to waste it. As soon as you defeat all the enemies, the latter will automatically enter the standby mode, come up and press e, there will be a mini-game where you need to click on the squares in the correct sequence, after which an inscription will appear that this enemy has been added to the gallery.
2) Bosses, try to stay away from the boss and you can use abilities here. Since the bosses in the game are different, I can't write much about them.
3) Try to look for chests on the levels (there are a lot of goodies)
4) Keys, bombs and money you will find at different points on the level (sometimes at the beginning).
5) Do not use the bomb against enemies (it does 100 damage, which is very little). There are locations on the level where some places are covered with iron boxes (they cannot be broken by normal attacks). Use bombs to break them (sometimes buffs fall out of them).
6) Keys are keys, needed mainly to open chests or doors.
7) ATTENTION. If there is something on the level that opens for hearts, never open it (this is not profitable).
