Ohh, okay, thanks for your replying. Looking forward to the latest version there ;D.
BTW, I think this game has some similarities with the Jack O Nine Tial( not sure if you know this game or not), that game is also pretty fun to play with.
I suggest that you could add some main/side quests into the game or add more ways to sell/submit slaves instead of the want list in the market.
Then add some special item or equips that could loot from the missions or other ways which could add some special effect to players( like slowly gain health or something like that) to make to gain more fun to play with, so players will willing to finish the mission that would cause injures and decrease the slave skills.
Moreover, the girl packs are amazing jobs done there, which has given us a greater immersion in the game. (most others games just provide random images that break the immersion a lot.)
