how i beat the game was by constantly asking him "Look Around" and he gave up and let me out of the last room, which was the room where i saw my own blood.

I found that if you max a turret and sell it you make more money that it cost. So when u have the money to upgrade any tower to 5 do it, sell it, buy it, upgrade it, sell it, and again, and again. I did the last level with all my turrets lvl 5(rockets and lasers) +1 keep this comment alive. In addition: To start this method u need at least $6.100 $100 dollar turret gives $450 extra (Need $6.100) $400 dollar turret gives $600 extra (Need $12.400) $1000 dollar turret gives $500 extra (Need 31.000) $2000 dollar turret gives !$3000! extra (Need 62.000) $4000 dollar turret gives !!$6000!! extra (Need 124.000) There is logic in prices, not in money back guarantee xD
