very good.
I thought you had created a non-win scenario in the funel room.
then it struck me.
I could have kicked myself :)
what is there to prevent trapping the player. I mistakenly thought was part of the puzzle.
which threw me a bit.
I liked the way the beggining & ending merged :)

twice I have gotten stuck in this level (as far as I could tell), the cube got sucked by the red funnel all the way to the generator, and back in the original room, the button that should destroy it and drop new, was already depressed and would not work (also it seemed like to get there the cube was going through grates like it shouldn't)

Thumbs up for a great map, but I seem to have seen this before... with same name? Anyway, I liked it a lot!

Clever. I liked that one
