The video below shows the route. Basically 2 techniques are used to be able to get all 3 cubes out of Floor 2 to get the star in Floor 3. EDIT: it saves around 10 minutes.
The first is a 'guided slide' that allows you to stay grounded while moving to a cube. Simply look at a cube to get the guided feet, pause the game, hold space, unpause, place the cube close enough to you so that it interupts the slide, then finally pick it back up. This will allow you to bring objects through the purple field.
The second trick is more complicated and inconsistent. I try to push the cube as close as possible to both the purple field AND the doorframe. It works best when the cube is in that snug position. Then use the doorframe as a means to block the guided jump, do the 'guided slide' technique, and hope that you teleport far enough to dodge the purple field. Sometimes you'll make it as I did in the video, sometimes the cube will be forced out of your hand but will land on the right side. Most times though the cube will be forced back indoors.
This should allow Messenger% to become shorter than Transcendence, so HYYPEE TriHard
Wow! That's probably my favorite glitch in the game! Great job!
If only gates opened once you got past them. You can use 2 boxes to jump the star gate in B. But as far as I know, you're stuck if you do so.
