Portal-Free Testing Initiative: Agility Platforms

The Aperture Science Portal-Free Testing Initiative was created to see how test subjects would react when being put in a completely portal free chamber after solving dozens of puzzles using the Handheld Portal Device. This particular course focuses on jumping between platforms and features a one-time opportunity to use a portal at the end to test potential endorphin releases in the test subject.

[This is part of my series of maps experimenting with portal-free chambers. It might seem counterintuitive, but it's a nice mapmaking challenge. Like my last map "System glitch" I try to show glimpes of actual testing chambers to remind players of what they're missing.]
