Button Waltz

A true portal-based logic puzzle. It starts simple and gets progressively more complex as you acquire new testing elements. Dust off your basic flinging skills, grab your ASHPD and get ready to exercise your brain.

Oh, all right, you get to knock over some turrets too. Happy? :)

Revision 2:
- Altered the mechanism that dispenses the sphere to fix the sphere not despawning when the player removes the cube from the connected button. Now the player can't skip getting the last cube. Thanks Daniel!
Revision 3:
- Steam error.
Revision 4:
- Added a portal surface to prevent the player from getting trapped in the turret cage.
- Inverted one of the panels to avoid unintentionally deflecting the player into the sludge pit.
- Substantially reworked the final area to make the corridors less cramped.
