Oh, actually yeah! If you could see the color key info from the "How to Play" page in-game, I think that would be helpful (mainly suspicion and time). The only way to see it now is to quit the game first and go through the main menu.
The main other thing is that It took me a while to a) understand that the pieces on the table represented my game progress and that my goal was to get to 15, and b) that the purple numbers were how I progressed that. Admittedly, part of that might have been just me being oblivious at first, but worth mentioning.
Given more development time, there's ways to make these numbers-to-elements connections more clear through animations (like pulsing or floating the move number and zooming in on the game board as the board piece moves or something), but there might be simpler adjustments you could make, like maybe your board piece could be a closer color match to the purple UI element?
Again, I enjoyed the game a lot, and once it clicked it makes total sense! It's just the initial orientation to all the mechanics at play and what connects to what, which is almost impossible to gauge until you have people playtest.
