I just got the 4,16 cryptid and was puzzled for a long time :)
Hint: You need to get a living steve into a position, where you can push a dead Steve to the teleport on the left, refresh the counter and then move to the bottom teleport.
To get to the bottom part of 11,12, you need three Steves and the Rock on the left of 10,12. I think it was 2 above and 1 below, but could be the other way around. Its tricky to find the right way to arrange in 9,12.
I am missing the room 9,13... any ideas?
