Badass game.
I loved the style, graphics, the dark, portal-esque overlord feel the automated support system had...
I felt like the controls were tight for the most part, but sometimes the physics combined with how he was supposed to be controlled left a wonky, unpredictable feel. For instance there was a machine part near the beginning in the top-left of a room where I was to jump across some platforms that looked like wood, and no less than 10 times in a row was I unable to jump from the last platform to the part because of the way the guy hopped as he ran up the slope of the final part.
The flying gizmo was pretty cool, I didn't feel panicked or overly frustrated by him, which is great because I like games of exploration over speed and twitch reflex. But this was a nice combination and he kind of felt like a companion after a while, even though he was trying to kill me.
