Clever theme! The gameplay is pretty straightforward once you get the mechanic, but it's an interesting take and it's pretty fun to try and manage your time. I wish death was a little more forgiving, the game is more interesting the further you get but replaying the first 3-5 levels gets a bit repetitive and it's easy to make a mistake later and die suddenly.
I had initially intended to include the typical undo feature you see in sokoban games. That way you could reverse your death a few steps, or something. The first few levels generate so they can tutorialize the movement; I expected most people to only play once or twice. Nice to hear you played more than that (even if it dragged a bit).
