You shouldn't be abel to complete this TD! It is designed to be a "never ending" TD where you play until you have lost. The score is what you have to look at.
i never said i wanted this td to be completable, i just asked what level should be abou the maximum level that can be reached....(which obviously could even be calculated)
if gex now came and said, "in the next version i'm targeting for a balance that let's you reach about level 80" then i'd be pissed, cuz i already reached that level in this version, so the next version would offer me no means of satisfaction..
