Level 37 and 38 are the most challenging. The only let-down is the occasional glitch, sometimes when dropping a cube through a portal “unaccompanied” instead of coming out of the other portal it will simply fall through the floor to the level below. On level 37, teleport into the middle far left box put a portal in the far right one and leave the portal open in the left one just pick up the block with F and you can go right back to the far left room then just portal straight down.
