Moved the laser receptor for the 1st moving platform 1 block higher and made the 2nd layer (middle blocks) unportalable.

Raised the walls next to the spawn higher aswell.

Both of this was to prevent getting on top of that wall or standing on the cube and grav beaming yourself upwards into the grav beam and avoiding half of the entire chamber.

Fixed the button respawning the 1st cube.

Fixed grav beaming the 2nd cube to the start by repositioning the spawner.

Added more room behind the glass to make it easier to aim.

Moved the 2 lights for the 2nd moving bridge to behind the bridge ( a more visible location).
