The save system is awful and it just ruin the campaign. That is all I have to say.

You don't manually save, it just constantly saves your progress and you can't go back other than restarting the entire level. This would be fine for a game with level taking 10-15min, but it's really easy for the levels to take over an hour and of course the hardest part is at the end.
