Great update, I really love the split personality, it's also interesting to have a friendly yandere following you around, but watching out for her flip to yangire, you can only keep her nice for so long until she eventually switches to yangire. I really like the direction you're taking the game.
I do have a few suggestions though.
1. Now that players can interact with the yandere, it needs to be clearer to the player what phase she is, being intantly killed by her because I hoped that by taking a few hits would return her to yandere, is frustrating, so some distinction between her yangire phases is needed. Essentially, I think her abilities to instantly kill the player should remain under her permanent yangire state and it should be obvious to the player when she's in this state.
2. The new map is more interesting than the old one, but its layout is not really balanced well for the player, there's lots of long corridors, with little to no LOS blockers, and given the yanderes insane speed and ability to jump on your back the moment you turn your back too her, there's not really any way to to sneak around the map, or escape a chase, lockers aren't too useful either as her hearing is so acute and they're loud af. You can't really hide, and you can't really evade her in a chase either, so because of that the new map is less enjoyable to play on.
The player needs hints where she's located, such as footsteps, and only able to hear her talking when she's nearby, or on the same floor as you. On the harder difficulty she could be without shoes and only talks when she's talking to you or suspects the player is nearby because of a noise or something,
3. The player should have more ways to access the camera's, but using the camera's should also have the risk of alerting her that you're watching, as camera's in game could have a red light that switches on when someone is watching, this in turn could let the player know when the yandere is using them to try and find the player, to which, if she thinks the player noticed the camera being on, she could use a microphone to talk to the player saying: "I know where you are" or something.
4. Players should have more lockers and places to hide in, and keys should not spawn in them, they should be there only for hiding or escaping the yandere.
5. I think it might be interesting if in time a trust mechanic could be introduced, and the trust level can determine what kind of end the player gets if caught by her. For example, in her yandere phase the player could make requests which would allow the player to hide/escape, but if the player doesn't hide then she trusts him a little more, and she could be the one to make requests in her yangire state, if the player does what she ask that in turn would also influence her trust. In other words, her trust level will determine her final personality when the player is on the verge of escaping, and that might make for an interesting dynamic, and perhaps the AI can have unique advantages depending on what personality she gets in the end game.
All in all, great update, and I love the direction it's going, it just needs some polish.
If this game continues to grow in popularity, I think it might be worth considering a VN prequel which can explain the events of the game.
I did come across a bug though, you cannot pick up the cafeteria key when the yandere locks you in, it's a good thing she let me out after a few minutes...
p.s Ngl, the sleeping yandere was too cute, almost made me not want to escape.
Awesome new event, hope we see more interactions with her in the future.
Keep up the good work!
