NOTE: I've yet to be able to complete hard mode.
- The incoming missiles have tone to clue you in that they are coming but this may be a problem for hearing impaired users, there should be a visual cue as well.
- There is periodic lag, usually when a bunch of planes/missiles are spawned.
- Sometimes missiles come in huge clumps, some seem to spawn very close to the C-3800 which seems a little unrealistic unless they have some stealth systems.
- Sometimes the weapons don't fire and it's unclear what the problem is. It clears up quickly. If there are conditions that block firing, there should be feedback (text/visual/audio).
- The planes are really hard to see below the horizon, is this intentional? A HUD system would put something over them (red or green squares etc).
