Stuck in the starting elevator. I get Cave's announcement and then nothing happens.

There's some visible clipping in the elevator that looks like two copies of it are on placed on top of each other.

i threw the cube into the hole on the glass wall

There's some nice touches here, such as the visual indicator in the sky when you have your portal gun on! I also appreciated the originality of the space theme. However there were multiple problems both visually (something's wrong with how the floor buttons are mounted onto the button bases) and with the logic (sometimes the cube doesn't fall onto the faith plate when it's supposed to; the last move doesn't work). The last one is particularly problematic, as it really doesn't take that much effort to play the map after publishing it and ensure that each move can be performed properly. I also had the issue where the entrance elevator didn't go up until I restarted the map; it looks like somehow there are also two overlapping elevator models?

The intended solution does not work but it is solvable, sry ):
