I gotta say that after playing more runs, the game definately becomes easier.
Just get the dresses and spam dmg in all of them, the games becomes a cakewalk, cause the entire core of the gameplay is based around dps.
Capturing all the monster with each girl, getting the art for each girl with each monster etc, that's another story. It's a huuuuge grind I dont feel like doing, so I'm thankfull for the full unlocked gallery some hero posted here.
Ill add that, as I said, based on the dps factor of the game, I dont think most unlockable abilities from the dragon lady are worth at all. In fact I dont think any of them are as good as the original ones.
Imo, best habilities are
Swordwoman: power sweep (triple dmg) or other habilities not relying in red zone (most swordwoman abilities are garbage cause they need enemies standing in the red area, which you never want, you dont even want them in the blue area if you can prevent it)
Ninja: the one that pushes an enemy into another, double dmg
Archer: trip wire or bear trap, double dmg or losing turns
All of those are base habilities.
Also, since unlocking an item or an ability permanently puts them into the rotation, if you dont like an ability or item you bought, tough luck, you are screwed forever, which I dont like as a design.
This could easily be solved with some kind of magical book or something of the sort in which you can check what the rotation is, and then there could be different options based on how you want to design it.
Example 1:
Base items and abilities are permanent and cannot be taken out of rotation, but you can toogle the ones you buy to be in the rotation or not, so you can try them out but take them out if you dont like them
Example 2:
There is no permanent item or ability, but there is a limited number for each of them, so if you want to introduce a new item or ability, you have to take out of rotation one already in rotation. Again, tooglying should be just fine.
