A very good remake but I'd rather prefer if you remade the original Crossfire, which appeared on Apple II. That one used much more interesting key control. AWSD keys were used for fire control and IJKL were used for movement control. The player character (robot) did not stop automatically at the intersections. You were required to press SPACE to stop it. This made it much more interesting than versions appearing on later computers.
