With no controler support it feels incomplete and is difficult to overlook. Movement is clunky, for example requiring inputs like 2 taps of the enter key to perfrom a backflip left and right arrow keys for movement and sometimes use of the mouse. I would highly encourage you to lookup the full list of controls to fully understand. There is a grid weapon selection view, left click will bring that up saving you from having to use the F 1- 12 keys. The game is playable but will take some getting used to.
