Thanks for the bug fix! I think that I am still stuck.... I got the high jump, pistol, upgraded call or whatever, and the phase. I went down and to the right where all the crystals are and took all of those enemies out... I think, but nothing happens. Maybe there is somewhere else I am missing?

Ahh yes. The enemies are not the final target. To win you have to destroy all the crystals in the chamber. If you go left instead of right in the tunnel leading to the boss, it's explained in a dialog and you'll get another power up. But that is the very end of the game so no worries if you don't want to play through it all again!
