This discussion is closed. We aren't removing undo from this game. Undo works as it should here, and Santorini should be upheld as a model for other games to follow.
The key points are:
Everyone can undo everything (unless secret information has been revealed).
Undo doesn't give additional time.
Undo is clearly recorded in the game log.
You can watch players take and undo actions in real time, just like in the physical world. This is a feature, not a bug! We did this very intentionally. This proves your opponent isn't dead or AFK and still actively playing the game. If you couldn't see anything until "confirm", it looks like nothing is happening at all. That intermediate time becomes very boring, and there's a lot more "are you still there?" chatter. The final result is quicker and harder to follow. The delayed visual actually makes the game take slightly longer because we're adding an extra step for the opponent to watch the recap while the active player just sits there doing nothing (having already completed the moves earlier). There are so many reasons why we didn't implement it this way.
