There's something wrong with Inquisitor AI. I was comparing with original Strife game, and found that there those robots are much dangerous, because they are able to fly all the way to player correctly, when he stands on some high place above them. In Vavoom, however, they fail and usually stuck jumping on low heights. On the "Labaratory" level you can simply avoid 2 Inquisitors or even make them drop into the deep pit in the centre of the map, and they would not be able to get out.
