At some point we switched to Snasm and Brief, which allowed us to use a PC for writing the software, running the game on an Amiga remotely.

But if you look closer, you will see that there are a lot more that sixteen colors in the game. The four bitplane frame buffer uses hardware scrolling. It is not redrawn. There is a fifth bitplane, that is enabled for only eight scan lines, to display the non-scrolling score and status line.
