I like the take on the theme (well, as said in the description at least; I am unsure if it got executed or not because the game isn't intuitive).
Ignoring all the bugs, I hate that part where if you tap outside the card area, it will say "Whatever you're doing, stop immediately! You're going to break the game and it'll be on you if you do it!". This is a game about accessibility. I know it might cause a bug, but please reword it and don't blame the player - especially since it's possible that the player may only be accidentally pressing outside the area due to the tremors.
Another minor issue I find is the length of how long you need to press a button/card. Though this is the paradoxical problem of accessibility for hand tremors. If the player has mild tremors, they might accidentally press incorrectly but can still press long enough - in which case, the game is doing fine. However, for players with severe tremors, they might accidentally press incorrectly and not be able to press long enough. Perhaps make the time to press the button/card shorter.
Note: yes, I do have (dystonic) hand tremors. When I get severe dystonic attacks, I get severe hand tremors and can barely press anything properly.
