Nice map!

1st map !
well, it is the best "Tag" Ive played so far.
only played 5 of the star rated ones.
but this one actualy has puzzles :)
& yes as Ætterna said, you can get past the crushers.
coming back with the cube was harder, without gel.
as they get destroyed, if they slightly touch the crushers.
but I got some gel later, to complete all parts of your map.
glad I did.
I used the light bridge method, in 1 of my portal 2 maps.
so I have to like that :)
returning my blue gel, near the end, had me for a bit.
for the crushers, maybe add a laser field or fizzler, on a timer.
so imposible to reach cube or get back with it, walking.
good luck /skill with future maps

Nope, they didn't. I just walked, stopped between the two crushers, and then walked past the second one.

How did you manage to get the cube from the left without orange gel? Didn't the crushers kill you?

I think I broke the map :p
Basically I just went to the left room, took the cube, took the one from the pit, put both of the square buttons, went inside, jumped up, bounced them off with the blue gel and finished the map.
Didn't have to enter the right room at all...
