you mean light fuse? it is randomized yes, but the correct combination is shown to you with post its in the office each night.
The gameplay itself is very based on FNAF games where you got pretty much 0 explanation on what to do, but you do pick up on what every girl demands from you with play time and looking at posters around the facility that give hints on each girl.If you have a question about any of the girls I can explain them to you
Well, not everyone attracted to this game has played FNAF, such as me and the one you anwser to. Sure yes, most parts of the gameplay are not so difficult to pick up as you said. However, there're some spots in gameplay that confuse new players, especially the combination to fix light fuse. Even, I have reached level 8, I still haven't know that the combination is on the wall in the office untill I see your reply here.
I would sugguest, to have a simple guide book at least if many believe making tutorial is unnecessary for developing the game, because it shares similar mechanism with FNAF.
I do agree that the light switch could use clearer instructions, like having the buttons also have the same symbols as the notes (this would also help colorblind people.
I personaly think that it is more rewarding when you understand something after trial and error and observation more than if a tutorial just tells you everything. With that said I do understand that most of the people that play porn games are not "old school gamers" per se and are not used to having to figure things out by themselves.
A good compromise would be if assist mode or maybe a new option gave you little info on the girls when you died (not specifically the one who killed you since that would mean Maddie would have no tips)
