Hi Smurjo, thank you for your feedback! It's the first one I've received and it makes me really happy to get it.
You are right about that part—you stop just clicking and have to start interacting with the game. I think it's a good moment to explain the interaction mechanics to prevent other people from running into the same problem. I can definitely add the reflection; it's a detail I completely overlooked.
Regarding the second part, I also think I could add a short tutorial when you enter free mode to explain the features, and especially to show the hint menu where you can see how to progress with the quests (inside the phone, on the top right, there is an app where you can see what to do next).
The game does have an English version; I thought it was configured to start in English by default (you can find the language option inside the menu).
Regarding the room layout, it's just as you say: there is no realistic geometry to them. I simply made them functional so players could progress, but it is something I would like to redesign at some point.
Your point about the backgrounds being too clean is a great observation too; adding a bit of clutter will give them more life.
Thanks again for the feedback! I'll be working this week on putting together the mechanics tutorial, and I've taken note of the other observations you shared.
Best regards
P.S. Looking at the screenshots, I noticed that the quest name isn't translated. I'll fix that too!
