My second favorite PP1 level of all time. Lots of great tricks and really fun to play. It took me two dozen tries to see how to get to the exit, and another dozen to get to 395. 36 tries in all, great level!
Hmm - it's possible to be 2 off by either filling the holes in along the top, or by filling the holes in from underneath - now to try and find out which way is correct ...
