One single layer, no sprites. Pushing Tilengine to its limits?

[System64]

Just one layer?? Let me know how...
Are you using an object layer?
There is another black layer with blue characters and drawing primitives. The moving logo sometimes goes under the text and primitives, so that layer is not a tiled layer where you can play with per-tile priority.
I'm curious about it :-)

Everything is on a single bitmap layer. If you draw stuff in the right order, you can emulate priority. The logo isn't a sprite either, it is a part of the bitmap layer.
But I went even further. What if we have 2 bitmaps layers... By using ONE Layer? And still no sprites!
Example with layer multiplexing.
