Super cool concept and execution! The game felt polished, and the movement was also extremely smooth! My only piece of critique is that the timer makes it a bit hard to play the game- I feel like this game wants the player to really think about where they want to move, but the timer being so short kind of keeps the player is a constant rush to move. In a way, this game has two timers- the one in the top-right, and the player's rewinding ghost.
But other than that, superbly fun and well thought out game! Good job!
