Okay so I am pretty lazy, and decided I didn't need all the life upgrades to beat the game (I only ever got two! haha). Only after the fact did I find out about the alternate ending which requires you have ALL the life upgrades.
My question is twofold: First, I have a save game near the end of the game, is it possible to backtrack and get the remaining upgrades or are there upgrades which are impossible to backtrack to (i.e. ones that happen during Dahaka chases or ones that are otherwise inacessible due to damage etcetera)?
Second, if it is possible to backtrack to all the life upgrades would anyone be nice enough to at least list the general areas (if not how to find them specifically) where I might find them? I have not been able to find a list of their locations anywhere.
To shorten any list I have already found the following upgrades:
Bottom of the bridge room (where you use the serpent sword to raise and lower the platforms).
Bottom of the garden tower (where there is a hard to see handhold you can drop down to).
