Fun map! Very unique, too. I was able to beat both the basic and advanced chambers fairly easily. The spheres are awesome!
There are some bugs with the map. Once you get to the final room, activate the button with the WCC, and let the "companion spheres" roll in, the puzzle is practically complete. You can jump up and finish. However, you can also use your portals from further back in the level, and return to the beginning. You can even climb up the pipes to the top where the spheres spawn. And if you hit that second button in the room that activates the spheres/pipe door, spheres begin to spawn repeatedly, eventually jamming the pipes and ruining the frame rate.
And is there supposed to be no slime on the Adv. map? You are able to walk and portal on the bottom of the abyss in the last room, where previously there had been slime. I almost felt the Adv. chamber was easier instead of harder.
Also, I tried the challenges, and got a minimum of 4 (!) portals for the portal challenge. Haha.
Anyway, awesome concept map, but several significant bugs. I hope to see updates and new levels in the future!
Not conventional; inventional.
