nice game, although I didn't understand how to complete a level after the rotating bars =/
Just remember that the spawn vessels (those machines that open when you cross by) are where you start after dying. You just have to play with that. Have you tried to reach for it in the last challenge? Thanks for playing!
If you're talking about the room right next to the one with the rotating bars[spoiler below], deactivate the floor and jump the reeincarnation pod, then reactivate the floor and die =D
