I can't believe there is no save feature! Unless you have several hours to kill all at one time, you'll end up having to restart from the beginning every time. Otherwise pretty fun! Needs a save feature!!!!
It would be nice to be able to continue later at the level where you last left off, rather than have to do all the levels all at once. Or to be able to go back and pick the levels that you've already finished.
