I found a bug in the wedding room. For some reason, the light bulbs and guests never loaded in, making two of the puzzles impossible.

Thank you. I will investigate it. it must have been a fault enabler/disabler.
in the meantime, I think if you reenter the room, it should fix it

I got the same missing light and audience bug. Reentering the room does nothing. There is something invisible that blocks the path, but nothing visible.

Also in the first part I coud not find instructions for which person does not need a hat

Henry is the one talking (letter tells you so) and so he does not need a hat

Hi. Same problem here with the lightbulbs and guests.

I edited your map, and found the solution for the ceiling/audience. Your "Visibility Activator" uses toggle, which means that if you teleport back to the first room, you disable everything. If you change the "Activation type" for the "Visibility Activator" to "Enable", the bug is gone. If you need to disable again later, use another "Visibility Activator" (set to "Disable") go disable the ceiling/audience at the end of the game. PS: I only reentered the last room, not the first, when previously trying to get them back. Hope this helps :)

Thanks :) Im currently away until tuesday, which is why it's taking so long. It will be fixed first thing tuesday morning

Finally got back and it should be fixed now! Thank you everyone for reporting!
