The movement is quite slow and floaty, you can jump a 2nd time in the air, there's no strafe jumping, the gameplay is kind of more portal than defrag, but without the portals,
It's not a bad game, I just wouldn't actually equate it to defrag at all.
I get 70-80fps most of the time on high settings 1080p on an i7 4770 and 750ti-oc, so performance doesn't feel great for what doesn't appear to be all that complex visually at all.
