The levels are more easier on hard mode but it still has that sense of difficulty. The only thing to be changed is the boss on level 11 because he is easily exploitable just by jumping over him.
The last boss on hard mode requires over 1000 ammo. Also, to beat him, keep a good distance but not to far so you can hit him and run under him when he jumps high, or just hop backwards cause sometimes he fires them off.
