Game used to run great, Played it about this time last year and got to the zero g levels and just kinda moved on. I went back to it a few minutes ago but I'm guessing there is was an update or something but the game is pretty unplayable. I everything runs smoothly expect for trying to right click for zoom, which sticks even though I let go of the button. I've ran into this with other games and can never find help so I always refund them, as I won't play games that make me went to scream as I get killed over and over from unresponsive BS. There any fix for this broken insanity?

Ask Microsoft! Probably a Windows update broke your games.

Contact GOG if you find no issues with your Windows installation as they should tweak things if needed in order to run on latest Windows.
