Released October 15, 2017.

*The button in the last chamber now uses a loop/retrigger mechanic to avoid it being triggered too fast, which caused the portals to change places. You'll notice a small delay but nothing that will affect gameplay.
*Added an emancipation grill at the end of the last test.
*Fixed some emancipation grills not fizzling physics objects.
*The soundscape in the last testchamber will now work properly.
*Fixed some non-portalable surfaces being portalable.
*Minor lightmap optimizations.
*The Dual Portal Device will now fire both portals even if you manage to break the last testchamber and switch portals.

Released October 14, 2017.

*I actually fixed the testchamber sign;
*Fixed being able to walk out of toxic goo alive.
