Hey Sezt, nice to see you here.
I first discovered HHotel a couple of years ago in the Lagoon. I really enjoyed it, despite the aforementioned "use the correct vocabulary" issue.
I didn´t have a walkthrough at the time, so I was scanning the Lagoon forum for people with similar "progress indicator number thingy" than mine, for clues.
The most frustrating part for me, was the "room hunting". That part where "even if you met all the required criteria, you have to enter some especific room at an especific time" for the game to move on. It also makes the replayability "not great". For me, it´s one and done.
I remember using a macro to sweep every room in order to find that trigger.
I was a patreon of yours for a minute there too. And played an early version of HHaven. I´m looking forward to see it finished, and give it one complete playthrough.
And when the trilogy is done, I really wish to see a game of yours in a new platform.
Cheers
