Hey, I said it was rough.

Go from the save point to warp point XVIII. Teleport to warp point XVII. Go south one level, the go to the left through the Virgo gate, through the next room through the Taurus gate on the opposite side. Go through the next room to warp point XXI. From there it's a straight shot to Omega. You may have to reposition the Virgo and Tarus gates first.
