Found the keys! I walked past that crate so many times but never thought to lower the camera… once you pointed it out, it was much easier.
To make interactive elements clearer, you might consider using lighting to highlight points of interest. A well-placed, distinctive light could naturally draw the player's attention and help guide them, along with the level design, of course.
That said, I understand you're currently focused on other aspects of the game and that this isn’t a top priority right now. Keep it up , you’re doing a really great job!
