I've added a stage select to the new release (v1.1). You can now start the game from any stage that you have previously completed.
Maybe I'm boring, LOL, but players would prefer if they can restart on the level they reached, for example if I reached level 3 (finished level 2), I would like to restart on 3, not play level 2 again to then play level 3.
I decided against that, as it would make it too easy to get to the end.
