I successfully finished Carlos route in easy mode. I am struggling on Adam’s route. I almost replayed 8 times and runs out of all the savings. By now I really doubt if Adam is straight as hell...
There's some information about the fifth route in the second devlog, here: https://bobcgames.itch.io/yags/devlog/64804/thank-you-and-an-update
Make sure you're running version 1.0122.0 or newer of the game.
