I finally got a chance to spend some time playing this game. I played a couple of solitaire games using the lane mode. Sadly I couldn't win, though I survived for 11 rounds in one game (assuming I understood all the rules).
I didn't have playing cards on hand so I created a numbered list for each deck (the appeal cards and the challenge cards) and used an RNG to "draw" from each deck. In addition, I didn't have any dice so I used this instead:

The flow chart on pg. 9 of the instructions made the rules much easier to learn. However, there was at least one section of the chart, shown below, which confused me at first because of the two **NO** branches:

Even with the flow chart, however, I struggled to learn all the rules. I started to become a little more confident with the rules after several turns, but even then, I wondered if I understood everything correctly. So, maybe the rules could be simplified somehow. Perhaps you could remove the cards and just have dice with a grid and pawns. In that case, you could have rules reflect various outcomes of dice rolls. For example, if one rolls three dice and the outcome is symmetric, as shown below, then a special rule is triggered:

That being stated, one of the more enjoyable parts of the game was drawing a challenge card and rolling the dice to see if I met the challenge. So maybe you could have two sets of dice, one to replace the cards â just an idea. I'm sure others feel differently about this game, it's maybe just me being intimidated by complicated rules.
Overall, a unique game, especially since you mix genres, and the rules, though complicated, seem well thought out. You get 5 stars for innovation.
