This is my entry map for the Summer Mapping contest and also my very first Portal map. I hope it will provide some challenge.

I'm just stupid.

So the question is could I complete the test with only one cube?

hi

You can complete it only with one cube. The second cube dropper is for convenience only

Hyperdetailed and painstakingly animated, to excess: the checkerboard look can become difficult on the eyes. Technical marvel with artistic shortcomings, as to say. Medium-hard.

Bug: you can get stuck if you throw the cube on the top of the glass corridor on the 2nd floor (I had mistaken that for an opening).

Thanks for nicely spotted bug, it actually was going to be an secret room but i did not have enough of time to finish it

Definitely have to agree that the map is way too busy visually, to the point where I had kind of a hard time identifying what was actually a portalable surface. You have a visible nodraw surface behind the panel that "pushes" the cube off of the first button on the first floor.

I'm playing custom maps and record my first time of playing them. So the run is not perfect and may not use only intended ways, but maybe it can let you see how other people may understand the map or you could just enjoy someone playing this map for entertainment.
Anyways, here is the recording:

I had a lot of fun with this map.

I did not like having to get the Cube by walking under the dropper - I never would have know that was the "Button" to drop the cube but lucked out.

I still do not know what that bottom button behind the fizzler does - I pressed it repeatedly but never saw it actually do anything.

Also - there are two Orange Gel spouts. Any reason for the 2nd one ? Just curious.
Thanks - it was a lot of fun.

Artistic theme only a NASCAR fan could love, but a decent puzzle nonetheless. The BTS areas were a nice addition, if only to get away from the glaring checkerboard for a while. As noted by others, I didn't see a purpose for the button at the bottom, unless it activates the return route. The two buttons for the orange gel had me scratching my head. Puzzlewise, this deserves a 4, but the visual assault drags it down to 3/5 from me.

I love all the beautiful visuals on this map and I thought it was funny that it starts you off by denying you entry into the test like it doesn't want you to take it. Those spike plates on the other hand are just plain cruel.
