cleverly designed with fun puzzles

The test was updated to work as I described it to below. That should prevent people from compleating the test through that method.

@nicklonium Thank you for the comment. I didn't think of the possibility of purposly emancipating the cube in the fissler. I think this could be easily solved if I link the first cube to a button that is also linked to the second cube which will emancipate it causing both cubes to reset.

It's certainly an interesting first test chamber and you've evidently put a lot of thought into it, however, most of the second room can be skipped and I never needed the laser or the second standard cube. The player can carry the cube from the first room into the second, portal it past the fizzler using the white wall round the corner and the high white tile behind the angled panel. Then place the cube on the flip panel pressure button so that the laser cube can be portalled back to the exit door side of the fizzler. Then the player can fizzle the first cube, go back into the first room to pick it up again, place both cubes on the cube buttons and leave. Hopefully that's clear enough.

I've got a little collection of chambers going and I'm always interested in feedback on each chamber or the collection as a whole. I'd be grateful if you'd have a look:
