Thanks for the video review :)
I see in the video that you have problems with the input controls. Have you used gamepad or mouse and keyboard? (the game is not very playable with the gamepad). In case it was mouse and keyboard, have you played from Linux? Some players who have played the game on Linux have experienced acceleration problems with the mouse. Is your case? Problems with the keyboard keys assigned? (I'm using standard FPS input layout).
I hope you can give it a second chance ;)
