Okay, I've been stuck on Just a Little Bit Shy for half an hour now. There are 24 lasers, but only 20 blocks. I've tested, and every laser counts towards opening the door. I've even tried it so no lasers are being touched. There is no opening for me to add more blocks to the grid.
Any tips?

@thatdudeguy:
For the kinetic ball/regenerating wall in the middle, you want to run (but not too fast), trying to make an opening in the wall that you can fit through. It'll probably take a few tries.

Also, in Four Different Exits, anyone have any tips for for how to get to the hall above the entrance hall? As far as I can tell, the biggest box + the yellow cube doesn't give me enough height.
