Card game breaks whenever you hit the stack twice before it does its thing, after that the queen floats above the stack, doesn't get in position again and isn't interactable anymore.
As for the positions of the pieces. I think I understood where everyone had to go, but maybe I had 1 wrong, and another piece wasn't perfectly on the right spot. It's not as if the positions are perfectly explained. I personally would've implemented a dummy situation and just made 5 possible spots on the chess-y board. Or maybe 10, but at least not being able to fail by having 1 person one tile off.
Either that, or I completely misinterpreted and was a dumb.
Other than that, I liked the variation of the different puzzles. Having the narrative mixed with the answer of the puzzle itself is also really brilliant. (I'm just too dumdum)
