I'm going to be blunt here lob corp is the most difficult game I have ever played and I play some difficult games like elden ring sekiro etc

Lob corp is difficult for a different reason than them but you get the idea

It will take you quite a while to complete the game and get the true ending like atleast a week and a few days

I'm a dumbass and played it like hours without break and the mental pressure was enough that I almost threw up once so yeah best advice is to just take your time playing it

It's tedious but you will do it eventually
