if your wondering how to get the achievement where you use a single vending machine 5 times heres an easier way to do it #1 go to lvl 4 #2 go to the room with the pipe saying watch your head #3 bang your head on the pipe some times(don't do this a lot because you will die if you do) #4 go to the room with the vending machine and heal yourself repeat banging your head on the pipe and healing till you get the achievement...
