I tried the demo last night and really enjoyed it, but I blasted through six levels in about ten minutes. I read in a review that the single player has 60 levels, which would shape up to roughly a couple hours, assuming the difficulty increases a little.
Question: Are the levels in the main game more difficult than those in the trial?--or does difficulty spike? How long does it take an average person to go through the single player?
I'd of course like to enjoy the mp, but I see on this board that it's pretty dead, so I'm guessing that's not much of a draw anymore. For 10 bucks, I'd like to at least get four or five hours out of it.
