Old puzzle but finally been able to update and streamline the map, including fixing an unintended solution found by Mevious. Celebrating with a release on TWP.

I really liked the puzzle , but I had one loose end.
Whenever I play a map with a Companion Cube, I feel like I should take it with me to the exit, but I should NOT be able to fizzle it as I walk through the exit door. Having ANY spare cubes at the end suggests an opportunity for further puzzle elements - in this case, perhaps a second button for opening the exit door. Or something even more elaborate, since I do like the harder puzzles.

Glad you enjoyed it. I know what you mean but I guess I don't feel the same way about companion cubes. When I use one it's only to separate it from a standard cube, so you don't mix up the cubes and fizzle the wrong one perhaps. The puzzle felt complete to me and adding a button if it doesn't serve the puzzle, just so you can put a cube on it is unnecessary in my opinion.

On another map (Prison Break 2013) I had three cubes and one sphere, the exit opens with the sphere and cubes help to get the sphere. I also had three cube buttons at the exit but then I thought that's complete bullshit and tedious work to carry all cubes there when the puzzle was about getting the sphere, so from that point on I decided not every cube must be carried around after it served its purpose.
