not fond of the ball throwing bit, probably becaue it takes me far too many attempts :P
other than that though, a very enjoyable map with yet another interesting new mechanic

I've played concepts like this before on other non-Portal games that had puzzle solving in them and there was better indication what button did what. Color coding the panels with the connected pedestal button would do wonders!

The futbol holder on the back wall didn't seem to make the ant trail beneath it light up nor did it raise the two pedestal buttons beneath the goo. I'm assuming that futbol holder was supposed to both of those things. I had to noclip and god mode my way down to them in order to complete the level.

Excellent concept, fits in nicely with the Portal spirit. I would however, appreciate a little more lighting and some autosave points on this map.

Great map! A lot of fun.

The goo was more a visual element than anything else. Do you completely clear your landing zones or can you save yourself by moving in the opposite direction of your fling?

Great map with nice puzzle element, just not too sure how the deadly goo comes in play in this one. I have several attempts with the map where I know what I was doing, yet had to do over again because a slightest slip on the walk. Somewhat frustrating.

Neat stuff, although it might've been nice to have an introduction to the new gameplay element. (Specifically the ball, which blends in very well ith the scenery.)

Maybe fog, not light.

could use more lighting

another great map, although i must admit your maps are starting to warp my brain a bit.

Great map. Make more like this, but make them more complicated.
