Your comment reads as if you didn't try to play the game for more than a few seconds.

I made it a few minutes, I admit it was boring. That isn't my fault. In a better designed games these things would be more obvious.

edit: OK I tried it again, got the gun, it autofires which still isn't fun. If I actually got to control it and had less ammo it would be more challenging. If that's a possible mechanic I couldn't see how to activate it. Still boring.
