Keep Good Weapons:

Always keep your eye on your Health Meter. If you are about to die, equip your most undesirable weapon. When you die, youll only lose the weaker weapon and keep your more desirable ones.
Smart Bombs:

You can only carry five Smart Bombs, so use them sparingly. Dont waste them on a mid-boss. Save the bombs for the big bosses.
Patience:

Sometimes the best boss strategy is to slowly pick away rather than go full on. The game doesnt give you a lot of lives, so try to be extra weary when fighting bosses.
