Stuck on "lighting a fuse"

[CapnSnowflake]

It's right after "Too many lasers" and looks like it leads to the yellow gun. You have to somehow keep the doors open but the cubes grow back too fast. I only have the green gun at this point. Help would be much appretiated

[Temzilla]

You have to take away the blocks that correspond to doors. You can delay the doors going up/down by taking a clue from the name of the chamber.

Then you have to shoot cubes to prop the door open, it requires a bit of timing.

@Prinny Oh thanks I've got it working. I figured it would be something like that, but gave up the first time.

Care to fill me in? I somewhat get the gist, but it refuses to work with me, so I want to make sure I'm doing things right.

[nixed]

same. i can get one or two doors open but after that it's impossible.

[jetuser]

yeah i cant get the "fuse" to actually disappear in the right direction

[Moleculor]

You don't actually have to drop cubes to hold the doors open, unless you want to go back through them. (I didn't try, maybe there's another connection/path when going through them backwards).

That doesn't really help matters.....

[CapnSnowflake]

What I did was made a fuse going out without curving. Had it one block away from the wall. Then just delete the block in the middle. And make sure your in view of the door when it opens. You can try and skillfully shoot a block to stop it. Or you can do what I did and just spam it until they stack enough to block the door. It took a couple of tries, just keep at it!

Theres 2 ways to the yellow gun. One with the many doors and one on the backside where you have to solve another puzzle.

[GibMe*]

we know how to hold the doors open....we know.ACTUALLY!
you have blocks infinite, so it doesn't matters if you place some blocks SOMEWHERE

[Willexan]

how do you get past "too many lasers" in the first place? stuck for hours...

[TK]

Squares and rectangles are the key to too many lasers. Also you need the green gun or better.
