(If he ever read this one, the guy/girl from last review) Yes Mazoq, yes you doing smth wrong + skill issue.
First of all, the harassment time of heroines is changeable in menu [better change the slider every new run when fighting, not in the hub or main menu].
Second: The game mostly rng so u better restart every time to get for each heroine a good skill(most or half of the skills suck, I know), for example: AOE skill, poison attack skill, and one that drains sex resist but can deal dmg(burn skill for Swordsman for instance). Every time when u beating mini boss or boss, or both[don't remeber about mini boss], u getting special money to buy skills, so they would be able to appear in next attempts/runs.
Third: Check that hole in hub, at the end u gonna get net/fishnet spells, catch monsters to see their lore, pattern and sex scenes cards(scenes cards, if u had sex with them and progress was saved). Catching gonna gave u new spells, I have spell that provides no enemy spawn for 2 turns. I catched 15 monsters (include some bosses) and I have all 4 spells, 3 of them is very important.
Fourth: If u succeed on checkpoint, DO NOT USE QUICKSAVE THINGIE THERE. Atleast for me and some other ppl it's bugged. I mean, in current version I can beat game in 2 hours at most.
Fifth: This game have a quite amount of "What if?".
Sixth: level up girls dmg and stamina regen only(u can try to upgrade walking too, since it provides 2 good features/mechanics)
At first, I was also annoyed. But thanks to my interest in art in this game, I still decided to play a little longer and I didn't regret that.
