first off I have to say the models look fantastic! they're the best looking ones I've seen in a fangame, the clothes on the animatronics are great, especially both of the Bonnies. the graphics are top tier, you can see the withereds' fur and the toys' plastic. Not to mention the inside of the mask, it looks like they actually grabbed a spare head from the back!
but the gameplay could be improved on, especially on the office. whenever you look around the camera has a mind of it's own, you drag your mouse to the upper left corner, you start to look down; you go to pull up the cameras, you pull up the mask; you go to look down with the mask on, it just doesn't work half the time! Sometimes it feels like your head is too big for your neck! But the you go to the free roam sections, and the camera works fine!
I also got to the epilogue, but I closed the game and now I have to watch the opening cutscene, play the Mangle minigame, watch the second cutscene, walk into the building again, AND play the arcade machine again! there should really be a skip button that skips to you going back into Freddy's.
Edit: Also sometimes the hallway just... disappears? it might be like when the flashlight stops working when a new animatronic walks into the hallway in the original. But there's no audio cue like in the OG, so I don't think it's that
