Finished the game a few minutes ago. 10h 45m play time, enjoyable but flawed, music will stay with me longer than the gameplay will. Not being able to back track to earlier sections is a big no no in this type of game. Ended up missing 1 Energy cell, looks like it was in the tree since that was 98%, was missing something else in there during the escape that shows on the map. The cell for some reason wouldn't show on the map even after buying the ability to show them all. I didn't care for the floaty jumping either. The escapes were all awful to, bad game design from earlier games, shouldn't have brought that junk back in 2015.
Biggest worry before buying was Unity problems and they definitely reared their ugly heads throughout the game. Stutters, got worse in the later sections, seems to have loading issues and there was some major slowdown in a few sections even though my framerate would be in the 200-300's when I went back to test the area with vsync off. Game was on my SSD so it's not a hd loading issue. Fell through the world once but it was to a section I had already been to so didn't hinder me any.
Good advice for anyone just starting, fill out the middle ability tree first so you can see those collectibles and secrets before sections get closed off to you.
I doubt I revisit the game to get 100%, only type of game I tend to play more than one play through of is Diablo types.
