There are checkpoints.

if there are checkpoints, why do i have to start over entirely when i die. getting my health back in between phases is NOT what i would consider a checkpoint. It is frustrating to have to start over and over if i make a mistake in what should be a short game with a little bit of erotic content and sit through what ive seen over and over as i learn each phase little by little. its a great game, i just think it would be a better experience if you could continue from checkpoint after a game over
