My first test chamber

In my first test chamber, creatively titled "Puzzle 1", I was limited to just what I had used so far in the "Courtesy Call". Still, I think I came up with a pretty cool concept. Here's the quick fact sheet:

• Mechanics: 
  
• Surprise, 
• Jumping (conserve momentum through portals), 
• Solving
• Goals: Exit the Test Chamber
• Space: Vast, tall
• Components (all from Chapter 1: Courtesy Call)
• Weighted Cube
• Pedestal Button
• Button
• Angled Panel
• Light Strips
• Observation Rooms
• Rules:
• You can't shoot portals onto black walls.
• The laws of momentum are conserved through portals.
• Some angled panels are on a 30s timer.

Thanks, Bea, for play-testing my first puzzle.
