Great work! The beginning of the game is perfect.
If you accept some suggestions, I think you should vary the gameplay just so the game isn't another "FNAF NSFW game". The FNAF gameplay (cameras and stuff) at night 1 is fine, considering you need to survive like FNAF, but I think that shouldn't be repeated... unless it is used for something else, other than for survival like in the first night. Something like using the cameras to see your "favorite animatronic" giving you a show would be nice, if you know what I mean ;) (like Mona, for example...)
Also, some variety of gameplay would be cool (like a Dave the Diver game lol), such as mini-games for each girl, dates (choosing what to talk, like a Renpy game, so you boost your affection/lust with the animatronic) and some horror gameplay (like searching with the flashlight, escaping from a animatronic or other thing in a maze... a animatronic fixing gameplay like in FNAF Sister Location would be nice too) if the gamer wishes to discover BonBon's story, turning the horror gameplay optional but necessary to reach the True Final.
I hope you read my comment and consider what I wrote. Needed to use some Google Translate to write all of this, hope everything is correct :D. Also, would a localized translation in portuguese be a plan in the future?
Great work and good development for the devs! 5/5 and God bless ya 'U'
