The inability to take back misclicks and errors you could at a table definitely makes the game harder.
“Oh I meant to use the top of this card, not the bottom,” or “I wanted to move over here for this thing,” are things you’d do all the time playing at the table. Here the software is like “letting you take back a move is anathema even though literally nothing in the board state was affected by it, YOU SHALL NOT PASS!”
As well as nerfed Stamina potions.
