Definitely enjoyable. One small note - the icon for the magnet fizzler, to steal a Portal term, reads to me as a smiley face, and I did not realize what it was supposed to signify until I walked through it like 3 times.
Controls feel pretty nice. Aiming felt like it was snapping to predetermined paths on controller, but that may have been a result of running the windows version through Wine to play it on Linux.
