Hi again!
So yes, SEUM is VERY different. It is a game where you go on a (some what) linear path, doing plataforming challenges.
Your game , although it has the dungeon gameplay part with the plataforming in first person, it has a lot of focus on the management part, as you said. So advertise that part more! :)
I played it more today, and the mechanics started to click. I got the hand of how the game works outside of the dungeon. Then I started a new game, to see the tutorial information again, and after the fact, I think the information on the tutorial is correct.
So I think is really a problem of too much information, and if you are not expecting it (like I did), you end up not taking it in.
I didn't understand at first that, the face on the mirror actually apears on the guests inside the dungeon, and you need to find the right one (memory part, as you said). Then you need to buy new traits, to unlock new guests. I didn't understood that, in order to visit the locations, you need to expend action points on the Action Screen. To me I was missing some menu option or something. But after I understood it, the gameplay loop is solid.
Perhaps developing the UI more, will help with that. One thing that I notice is that the UI at the moment is almost completely text. When you add icons to the traits, and the Female guest, etc. it will make it easier to absorb.
I'm thinking, do we need to buy the traits, and then, buy the female guest? For example, tiny body and green screen only unlock the Goblin, as far as I know. So couldn't we get the goblin automatically, after we buy the tiny body and the green screen? And that way you could add the text "buy traits to unlock new guests". make it an independent screen, etc.
Regardless, as I said, after you understand how the game works, it works. Comunicating all of at to the new players still needs some work, in my opinion.
Hope my ramblings were not too confusing, and you are able to get something usefull out of them!
