Im not digging the switches to third person perspective for takedowns.
Another, more important thing, stealth seems to be the least efficient way to solve the level. In Batman Arkham Asylum for instance, stealth was the best option because otherwise Batman was vulnerable. Jensen doesn't seem to have this drawback as seen in the first playthrough, yet stealth takes more time and effort.
Another VERY important thing, the glowing boxes and switches. I HOPE this is just the tutorial of the first level, and that they stop later. If you created multiple paths for me to explore, do let me, you know, explore, instead of guiding me. It would make sense in a fast paced game where details are easily overlooked. But if im CHOOSING to find a path of my own, don't hand hold me.
Otherwise seems decent.
