The main thing I would add to this game is checkpoints inside the level. It sucks to get within sight of the portal and then have to restart for the 30th time.
I love the little details, like how in the trophies the W in "Switch" is crossed out. I also like the backstory style, the variety of powers, and the settings options. I also enjoyed Forbidden Arms, but It made my computer lag, a problem I don't find with this game.
