thx i will correct that, wasn't intended to be possible

I was able to jump to the exit though, and then made my comment about only using one cube.

there is, since you got no chance getting to the exit if not threw the other side.

didn't notice the first time the button opened the wall, but the exit should be on the other side otherwise there's no point to do the other side.

There are only 2 laser Walls in this map. One on the Ground working as "Acid Floor" and one right after a button to unlock it. One solution to get into the right half is throwing a cube onto a button (pretty close at the location of the screenshot.

in the second picture up there, the right half of the map is blocked off by lasers

What do you mean by "blocked"?
It's possible to cross the hole map with the skills ya learned on the first 3 maps

I only got one cube, the other half of the map was blocked.

small update (mostly cosmetic)

after seeing your shortcut (i had to delete your link because i dont want it to be seen by other players), i can tell you: Good job! But i do think it is quite clear that the first cube isn't supposed to be used that way =).

I won't update the map to prevent players from using your way, since i personally think your way is a lot more difficult/dangerous/longer.

would be great, if your way is possible cause of a logical mistake in my design, i will try to fix it, if your just using clever tricks...well then i definetly won't =)

hmmm...
I replayed the map. I do not need a cube at all XD.Shall I make a Youtube vid and send you the link?

I just fixed the last few steps to prevent the player vom passing the last laser wall without the 2th companion cube thx @ Vtrap for the hint on that

What is the second companion cube good for?

Stage 5, the first actually "Non-Tutorial Map" will follow tomorrow at 1pm (+1GMT)
