Update September 1st, 2022

- a competent programmer has rebuilt how tiles get shaded, so movement is now less choppy

- levels are now loaded in the background.  This interferes with the music initially, but after the first few levels are loaded, it becomes much less burdensome.   More importantly, though, it removes loading times between floors.

- The new issues with the floor shading are now on the docket, as it works under a new paradigm and therefor requires different logic to act the same way as before.
