Stuff I'd known before starting the game:
1) Switch to keyboard movement controls. You'll live longer.
2) The knife is epic. Fastest attack speed, bonus to money earned, and low upgrade cost make it the only weapon you'll need for a good while.
3) The barrels explode. I know, it doesn't make sense to me either. But they give you 50 gold each, so they can be a significant source of income in earlier missions. The light brown baskets also give you a few extra coins.
4) Click and hold to shoot when using towers.
Good work...your game has left my palms, my keyboard and my shirt drenched in sweat, and myself, burning with an irrational hatred of bears, bunnies and flaming skulls, after two of the most intense minutes of my life.
Martin Luther King Jr.: African-American civil rights activist. Did not appear in this game.
Martin Luther: Thoroughly evil German monk who split the Christian Church in the Western Europe for his own selfish purposes and instated several heresies that have to this day not been reined in (in fact, today they are more rampant than ever) and led to the immense moral laxity in modern Christianity. Known for his Ninety-Five Theses, 43 of which were unquestionably evil and heretical. Gleefully shivved by me multiple times in this game. Get your facts straight.
