some effort went into this, but i experienced technical difficulties. At first i didn't know how to click on the cards. Turns out i had to click on the top of these. then the mouse was very floaty/laggy. I think the bevy team added something for that particular problem https://github.com/bevyengine/bevy-website/commit/14fbf1e1681aa71a6446d26d301538... Too bad i can't see your code, i'm curious about that issue.
Anyways good atmosphere in that game, and nice transitions.
