Hi! Thanks for your comment! That invisible wall is actually part of the story — there are no items in that room. As for the objects, I tested it with 4 different testers, and they were able to find them within 2, at most 3, attempts. Also, the fact that the game is very dark is intentional to increase immersion — a phone doesn’t light up like a flashlight, and that’s common knowledge! I hope you can give it another try!
