Q1: Yes. It will be for the full version.
Q2: Yes.
Q3: Yes.
Release: At this rate, I will be pushing the game to a much later date. A 2023 release isn't realistic now considering the work that needs to be done and the limited time I have nowadays. However, I am considering releasing a demo version which includes Month 3.
Reputation: It will be introduced starting Month 3. It will unlock sidequests, influence options with other NPCs and quests, and unlock other features as the game progresses.
