Thank you for the feedback!
Yeah, we are trying to think a way to implement a visual indication for the current layer, most solutions come with drawbacks that are hard to solve, for example, if we change the color of the player it could be harder to know exactly where you are in general, because it could be confused with the background or level geometry colors.
Some other Ideas we had include changing the outline or adding a UI indicator of the current layer, like a colored arrow on top of the player's head.
