The only problem with Harem Hotel(Which was fixed in the latest update iirc)is that there are so many eevents locked to a certain time of day that without a walkthrough the playtime shoots up to a ridicoulous level. I don't want to jump between rooms after every cycle(Morrning, afteroon, everning)just to play the game. It makes it a boring and tedious experience.
Now, for games that lock you out of a path when you make the wrong choices I always use a walkthrough. I don't have enough time to be reloading saves to find out where I went wrong, i'd rather get through an update with a bittersweet smile on my face(Bitter that I need to wait for an update, happy that I got to play a good game)rather than a face of pure boredom while I raise my hand and say, "yay".
This section isn't aimed at you:
Although I would've liked the update to have been out 2 months ago, the dev can only do so much. I have concerns about the game, but unlike others I understand that the dev is doing the best he can to get an update out and ready while juggling a job at the same time. I won't complain about slow updates because the dev had stated that unless his patreon income reaches more than the money he makes from his job this will only be a side-job/hobby.
