Ok, after playing today and beating the first 2 nights and almost beating the 3rd and trying the first night of Freddy 2 to see the difference and all the mini-games I realized I was wrong about a few things.
-Enemy AI routes are random. There are specific rules to each character like Rabbit only goes on the left, Chicken on the right, Fox when triggers sprints to the left. But within that they can go whereever they want whenever they want so they can hang in bathrooms and then back to the main room and down the hall whenever they want. So you basically need to keep an eye out for them (or ear, but I find they're pretty quiet so it's hard to rely on that) and shut the doors as they walk by and re-open the doors after they've passed to conserve battery. Replaying the first night I was able to clear with still having like 30% battery, but 2nd night was like 2% and 3rd night died a little after 5am. You pretty much just flip between the cameras and track the AIs so you're aware when they are close and can trigger the doors on/off on each side.
-Freddy 2 actually is an entire new location, so new building layout, new enemy AIs and the gameplay is pretty changed up. There's no doors instead there's 3 openings that can kill you (instead of 2), a vent on the left, a vent on the right and a hallway in the middle. I didn't quite grasp what you're supposed to do but something about keeping them in the light and winding up a music box to keep them from janking you.
-The mini-games are fun. There's one where you have to take the animatronics apart and repair them and put them back together but if you do it wrong you die. Kinda like taking apart an explosive. Then there was this vent repair one where it's basically a VR escape room except there's a monster in the vent and you have a flashlight attached to your head and looking in the 3 vents causes the monster to crawl back. So you're solving puzzles while looking between vents to make sure there's no monster approaching. Pretty fun. There was another one about closing doors and one about copying a bear that I didn't really understand. These games have pretty poor tutorial/instructions.
-The game actually isn't too bad on the scare factor once you get the hang of it and have died a few times since it's more just a tense puzzle game and when you die it's more annoying when they jump at you than jump scares.
-The VR is really good and there's a lot of content, but the one issues it has, at least on PSVR is the lack of room scale. For a lot of the mini-games they think you're sitting on a chair that is in the middle of the room with nothing around you so you can reach down and grab items in front or behind you. But if you're sitting on the couch you can't reach through the couch to grab things on the floor so I had to do a lot of re-positioning and moving around to grab stuff like that. For the main games since you just have the door/light buttons on the side and the cameras buttons in front it's not really an issue.
Overall pretty fun, gonna try to beat Freddy 1 before moving to 2. There's also a lot of hidden stuff in it so I'm curious what it is.
