I must say, the game is shaping up to be fantastic. It really got me intrigued, and I have already Wishlisted it on steam. The atmosphere is great. I love the art direction you have taken with it. Looks very retro, in a nostalgic way.
I think i have gathered all the clues I could possibly find, because the game let me "enter" the museum (not enter, but told me the demo was over).
I really like what you have so far, and I hope you can deliver on the quality!
I can only think of two feedbacks here:
Whenever we talk to a character, and we select an option that opens up to questions, after I select one of the questions, if I want to ask the other possible questions, I need to select the same option that opens the questions again. It would be better if after the chracater answers one of these questions, the game put's me back at the questions menu, so that I can select the remaining. If what I'm saying is a bit confusing, I'm refering to the questions as in the print below:
It would be nice as well, if there was some kind of indicator, to know if a character has something new to say regarding one of the questions that I have already asked.
The other feedback is that, I think I've noticed some typos here and there. Since this game is dialogue heavy, it would be worth to run all your dialog and text under a program to check for any typos. Could be chat GPT for example.
That's about it! Game is great. Keep up the good work!!
