Yeah, I've beaten the game and done all the bosses now
Only 1 trophy away from Platimum too. Yay !!
But yeah, Anchor was a bit easier after completely filling my skill tree and becoming a telekinetic badass
(I'm also quite the crackshot using the Pierce gun now too, which helps)
Its amazing that even after about 30 hours of gameplay, I was still finding new little nooks and crannies with stuff in while floating about.
I agree about the map though.
For my first hour of playing the game, I thought I was using it wrong or something. It's about as useful as a chocolate fireguard.
But then I twigged.... just use it to get a general idea of which compass direction you should be headed, and just follow the in-game signage instead. MUCH better.
But as you say, it could certainly do with indicating a bunch of other stuff too.
