This may have been commented earlier but it bears repeating: "Insanity is doing the same thing over but expecting a different result" Nice meta-commentary on idle games.
There is an element of luck, but good estimation skills will prolong your game as you can minimize the number of lives lost per level. Get lucky on a later level and you're going to do well.
