Part of it is that I’m more used to moving with WASD, so using the arrow keys was an adjustment for me, but most of the confusion I think had to do with not understanding the mechanics or objectives, so I didn’t understand what I was supposed to be accomplishing by hitting certain buttons. The biggest examples I can think of right now are 1) not knowing for a while what the numbers on the tiles meant (I thought they were attacks/abilities and the number was how many times you could use them) and 2) thinking shuffle tile meant that after you placed a tile you could push them around the grid
