I came to comment on the same... I grew up with CGA graphics for my first games, too. It was, in many ways, worse than no color at all. But the jarring visuals and the feeling of it will always stay with me.
I don't know why this site calls CGA "16 color" (the size of the CGA palette, of which 4 could be used at a time at this game's resolution), while also calling EGA "16 color" (when EGA uses 16 colors at a time from a palette of 64).
I fed this question to Gemini (compare CGA vs EGA) and it made the same category error in its distinction, calling both "16 color". So, to the human that didn't check their slop site, maybe you should fix that.
You could see all 16 at once in CGA text mode, and in "graphics" modes derived from that: https://youtu.be/G66KL-hxxKI
There were two PC floppy versions - 16 colour and 256 colour. The 16 colour version had fallbacks for CGA and Hercules, the 256 colour version had a fallback for EGA. So the CGA screenshot is the 16 colour version running with CGA fallback, and this is also why there's a set of "256 colour EGA" shots. It's a little confusing, but it's correct.
