You could either make another super simple level, or show them in the first level, but make it slow motion and highlight what's happening. Maybe the most important is getting some people to play it next to you and ask them if they understood. I had to rewind the video a few times to get the ideas, but then I suffer attention issues (ADHD). I'll tell you a little more of what I experienced. First sight, so many colored blocks, where is the center of attention? I built a model of the rules of the game, it's a gem swapping game! So all those blocks are there for me to control. Oh, a block is throwing rays, did it just explode? Wait, there is some text in the middle, couldn't read it because my attention was on the suroundings. Now I had to rewind many times to read the text and pay attention to the details, so I could modify my first sight model. The only way around this is cleaning up the level and leave a single mechanic and effect at a time. I like the bottom text that constantly replays the instructions. Maybe add a 3-2-1-Go! at the very beginning to warm up attention on the middle text.
