Just bought Arcade Upgrade. Mindsweeper rocks, I suck at MMR on my laptop where Fn is where Ctrl should be. (MMR is Measles Mumps and Rubella, which is a jab that innoculates you for all three)
barfman's method works really well, so I will keep it alive: the easiest way to kill him in every level is to put the trampolines on the ground 4 of them and spikes on the ceiling and if u have the money than put the guns on the wall and put the duck on the side and it may take multiple tries but it works for all the levels
