Thanks for implementing cube-hopping as a legitimate testing element! The twist ending was great, too. The only critique I have is that this would have been a great time to use the Companion Cube, which is something I almost never say, and speaks well of the design!

Ok now this one was easy. Thanks for creating.

This was nice. I actually did forget for a hot minute about the cube respawn system as a way to solve the test. This wouldn't really make a significant test on its own but it seems to be part of a series of tests, and this really does feel like a nice intermission test. Thanks for posting this.
