Hey,

was the cube jump over the first pit intended? And do I need to use the cube freezing bug to solve the last two chambers?

The cube jump is the coolest thing I ever saw. Too bad it is IMPOSSIBLE to do. I tried so many times and landed squarely on the cube - however I am getting no "lift" from the floating upward cube and cannot get over the lip on the far side.

Dude... I spent like 15 mins on this... you make an explicit glitch part of the solution???
