This game has some huge pros: sex combat with monsters & good art. This perfectly fits my tastes. Unfortunately the gameplay balance is broken in all the worst ways in this public demo. First there are two bugs that really ruined the game, first bug was sometimes the fountains were unclickable, second bug is that sometimes the church would charge me 100g for the 50g purification. So when I was starting out I kept getting stuck in this horrible loop, basically I would lose a venture, but then I'm sent back to the town. But I wouldn't have enough money to get rid of the lust, so I would go to the forest again already lust broken and it was basically impossible to get enough money to break lust AND level up. I spent hours not really progressing.
Then I figured out a gold farming strategy that made the game really easy. Basically don't even bother with the church, don't bother with loot, don't bother with fountains. All I did was go into the forest with full lust, lose to the monsters in one turn, get 100g, and then did that again and again. Unfortunately this game unlike most sex-combat games don't have a sexy endscene on defeat, so I couldn't even enjoy that, I was straight up just grinding this game to see if I could break the loop.
I was constantly levelling up and I wasn't engaging in literally any of the game's content. Chests were almost never worth it, fights were almost always too long to be worth it. It basically became a clicker game with no strategy or challenge, the only skill needed is patience because 60% of the rooms in this game's dungeons are literally empty of content.
So here's how IMO you could make this a fun game (and honestly it needs some pretty drastic gameplay changes.)
Firstly, SPEED IT UP, attack animations, walk speed, and opening chest animation takes forever!
Secondly, make chests worth while. Half the time I would get nothing, the other half I would get not even enough to pay for one church session not even with the best gold pull. There should be a risk vs reward element, where if you keep searching for chests and escaping strategically to the town it should be feasible to progress without being lust broken. But since chests are just filled with dust, and you don't get gold immediately after a battle, it makes no sense to retreat because you would just lose out on the money you would get from being defeated.
Thirdly, change how lust works. Lust has this double randomized effect, where sometimes it would just randomize the attacks, and sometimes it would just skip your turn and play an animation. RNG is important in this type of game, but you already have random dungeons, random loot, random crits, random misses, and damage ranges. When you can't even choose what move you are going to do it's not a strategical challenge anymore, it's instead a dice rolling game. I would recommend you play Dirty Dungeon to see in my opinion a very fun and balance sex combat turn-based system.
