No walkthrough... The Journal pretty much guides you if you follow it. Check each girl if you're not sure where to go or what to do next. Make sure you visit them all shortly after - if not on - the day listed for that scene in the journal. If nothing happens, visit a different girl first and come back later.
The pregnancy stuff is somewhat optional with a couple of the characters right now... We will implement an OUT for that later. Right now, it plays a part in setting up the Player/MC choice.
The branching paths are LIGHT / DARK - being FIGHT the Organization or Become a PIMP... There are side branches with secret endings for fun. The main story does have a split for a side character whether she becomes corrupted or is saved based on player choices...
0.8 will have the big boss show up and the choice between Light or Dark. Right now 0.7 is simply expanding main and side characters in preparation for that.
Regarding various KINKS ... We hope to embrace as many kinks as possible in LTA. Some players love them,. others wish they never existed. NTR, Pregnancy, Anal Sex, Bukakke, Lolis, Incest, and others... most are avoidable. A few are part of the player path choice or will be in the long run.
Jamleng and I will write the game using the kinks we enjoy and a few we would rather not, but know many fans love. As you can see in my signature, I have my personal preferences for gameplay. Jamleng has others. We have both vanilla and hardcore mixed in here. The plan is LEWD content all around.
