[WIP] [SP] interchangement
I absolutely adore this map and I solved it WITHOUT fizzling any cubes.
It involved one semi-ninja move where I had placed the blue in the ceiling of the room behind the fizzler with one cube on the button and the other cube on the far button that kept the fizzler deactivated. I then went and got the other cube that kept the fizzler deactivated and dropped it into the room so both cubes were there with the blue portal still on the ceiling.
Then I jumped the gap by shooting an Orange portal into the floor at ther far side of the pit . . . jumping to the far side of the pit and through the Orange . . . down through the Blue in the room behind fizzler (now with the 2 cubes in it) . . . as I was falling shot the blue in the floor to then sail up and onto the other side of the gap. I was then outside the room behind the fizzler which had both cubes in it and it had the Blue portal intact in there.
The rest was just jumping the other gap and getting to the 2 buttons, and then simply placing the 2 cubes there while retaining that Blue portal in the room behind the fizzler. The last part was the same as everyone else.
I would post up a video but since the last post was in May 2012 I do not think anyone will ever see it. BTW - your other map, :"SecondTest" is also awesome. Seems you have stopped map-making - so sorry to see that but it is a lot of work.
