New usage of environment

old but good !!
the probably intended way: https://www.youtube.com/watch?v=grt3D5h-_Gs

I have absolutely no idea what all those funnels were for in the middle area. All I did was raise the stairs, grab the sphere, make some portals and funnelled up to the last room.

REALLY enjoyed the first room once I figured out all the permutations (:

Last room was giving me fits until I realised all I had to do was use the environment to toss!

It's very good, but too logn to start it all again if you die. Pleas, if you can, make checkpoints betwen the chambers if you can

Ok, I just saw 1 more change (sphere to sphere button makes funnel to room 3 work, thats good.) I now have to swap the cube for the sphere as intended. But I can still bridge across as shown in screen shots or just make use of the new mats on the exit side. Think carefully before you make any more changes, fixing one thing can have big effect on the rest of the puzzle :) (As always feel free to delete these coments when read and/or fixed)

Ok, the demo would have been better but here are my screenshots

You can move across the other funnel in your way. Also the (block thrower stopping) fizzler looks kinda ugly :) can you put some kind of obsticle on the far side instead?

(i'm not english so i hope this post will be easy-to-follow!)
Your "home made ball-launcher" is a great idea !
But there's some things to remove : The laser is hard to set correctly in front of laser relays (perhaps moving the emitter on the opposite side of his square can work)
The player can be trapped against the cube dispenser on the roof of the 2nd room, if he stay too long on it.

You commented a map of mine, thanks for the constructive advice, I updated it now, and also the maps of the trilogy of it.

I've done some minor updates, but editor limitations blocked most.
Hope you enjoy and thanks for commenting

@chrishrly: I cant dl your data, can u send a screenshot?

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=122227290 please play this chamber. look at the description

You dont need to use most of the stuff in the second room. You can actually just throw the ball right over the pit and onto the button. I actually had to replay it to realize what the rest of the stuff was there for.
