It's alright.
Honestly I don't really like the designs for the girls, they're not really my cup of tea as I think they're way too exaggerated to really be that attractive (and the way the robot parts are done makes them look more like furry cyborgs than animatronic or robot girls, especially since they have no separation in the joints at all).
It's also not very engaging as a game because it falls into the same pit as FNAF 2 where 3 characters are essentially the exact same and don't feel special (and the pacing with adding all of the characters by night 3 feels a bit strange.)
And honestly? I could say more, to be honest, but I don't really care to. If anything I'm honestly just happy to see a FNAF H-game that actually gets finished and released instead of a night 1 demo (that's also just a clone of FNAF 1 anyways) that gets abandoned. I can't say I like the game, but I'm glad it's here.
