This is actually one of the first maps where cube-flinging works quite well. I've found it to be a pain in many instances, but seeing that you only need a single fall in the second chamber and that you have perfectly aligned portals in the third chamber, it works really well here.
Accelerating cubes through "portal-tunnels" is usually what makes this impossible to do, but that isn't needed here.
iWork925: I enjoyed the map, but it is true it needs fixing. But we tell you because you can make it! And in the end it's your work improving, not ours. You'll see how positive are people once you implement fixes, like rethinking the "puzzle" about flipping a cube in a 3X3 room without ledges.
how are you supposed to solve this chamber? Is the above video not the intended way?
Ah you bring this back from the dead and on my birthday. This map is so old and shit i don't really know / care.
