This will contain spoilers and first part is a guide to get you through the weeks to get to at least what feels like a good ending path.
For the first week you should work on maxing out AI programing and paranormal. you need to do 2 peranormal research on your own and 1 with goldie on your side since she is gonna boost your reaserch from 100 to 150 and wanna get that to around 400 points to get access to the peranormal shop and there you buy everything and from that point on goldie can help with research on peranormal. The pendant will help you get lexy on your side and it will help you uncover more about whats going on plus she can help you with research when it comes to lockpicking. She will boost it from 100 to 150 so focus on lockpicking when at home, otherwise push research on missing people when in the office. You might need to do a few more in the office but will know when the new update comes around. You also want computing around 800 points before talking to fexa or afew less you need to help fexa and chiku but you should push it as high as possible.
So 1st unlock goldie focus on peranormal to get to 400/1000 (before you go shopping) and computing to around 800/1000 (before next week to help out fexa and the girls. They will need help the first shift second week) and then max out paranormal when at home with goldie for the first week. When at the office push computing to 1000 and when you unlock lexy push lockpicking when at home cause she helps you with that and in the office push research on missing people.
This is as far as i got based on the current version of the game and you are gonna find two fun times going this route.
Enough of a guide and thoughts on the game. The game it self is great. I like the mistery behind the plot of the game to uncover the dark secrets it has to help out the girls and save them. I also liked lexy being one of the animatronics that can end up being your companion and not like someone who is allie with Mr. Smith. The progression and the story it self so far its very interesting and cant wait for the release of the game.
Keep up with the good work and we will see what next update will uncover.
