As someone who has restarted the game 5 times in a week, here's some advice for new players.
1. At the start of the game, choose martial art. This skill is necessary even though the game mention optional. Aquiring this skill later in the game is quite painful.
2. The attribute to pump up at the start is fitness. With martial art, you will only need 50 fitness. Without, is 75. This help to save quite a fair bit of robbed money. Knowledge and charm can slowly be built up.
3. Focus on targeted few girls at a time. If you cast the net too wide, the net will snap and you will end up with overlapping dates and many LP lost.
4. Control your s*x with Bree/Sasha until you are absolutely certain you meet the requirement of home harem. VERY IMPORTANT
5. I play this game on an android phone. If you make any wrong choices or trigger any event that you are not ready for, clicking BACK on the phone will "bring you back in time". This also apply for interaction that lose LP, or when you are scolded by Aletta and made 0 work advancement.
6. When you are suspended due to potential fraud, there is actual an 7days event that is triggered. The game doesnt tell you too clearly about it, but you should definitely complete it. Its more fun (for me).
7. After a 100% date with Bree/Sasha, you need to get their LP and KP high and do a booty call. This will fulfill the "Have s*x with Bree/Sasha" and then a d**k icon will appear when you talk to them from 20:00 till 24:00. (Apparently s*x during date doesn't count. Not sure if this is a bug.)
8. Quite a few girls (Bree, Sasha, Aletta etc) have conditions that will make them leave you completely. Tread carefully. A 20 LP lost (for Aletta's case) is a small price to pay.
