Ive seem to forgot the 4th life upgrade at the first gardens to unlock the tower (but a i dont really know how to get back there and b i dont want to have an old save game and i dont want to retrack everything back. Now im at the point after having killed the empress, but will i at some point be brought back through the follow of the game near the first gardens to try and obtain the 4th upgrade again????? I really like to know, because i everybodys talkin' about the alternate ending which requires all 9 upgrade.

Also ive seen some1 talking about him pushing the empress through a portal after he won??? but didnt happen with me. whats up with that??
