 ## pictures 
 if a level is made there is a possibility that it can be exported as a picture. You can use that picture format and decode it in the microcontroller then send it to the FPGA that sends that data through the VGA. the problem with this method is that a lot of data is needed to save a whole level (640 * 480 pixels) but different formats can have a large impact. For a better reference picture below.

 ### PNG
 PNG (Portable Network Graphics) is a lossless image compression format. Resulting in high-quality images that preserve all of the original data. Additionally, PNG supports a wider range of color depths, including 24-bit RGB and 32-bit RGBA (which includes an alpha channel for transparency), making it well-suited for images with a large number of colors or images that require transparency.
