Look, high difficulty is no problem, but if you need a step by step guide then it's no longer a "game" it becomes a task. Keep the high difficulty since it's clear it's important for your vision, but make the game intuitive. offer clear hints in game here and there, so that a PDF guide is not need anymore. using a pdf walkthrough destroys the immersion of the game.
Also I should point out something that was stated in previous comments, make the flow with some logic, 1 day can't consist only of work, eat, and sleep. everything seems chaotic. eating should take you from morning to afternoon, that's outrageous. that's not the proper way of implementing a high difficulty.
Take the advice or don't, it's up to you. Wish you all the best with your future endeavours.
