For every situation, a different weapon.
For every weapon, a different enemy.
For every enemy, a different situation.
Or, as >>15367256 elegantly put it, Git Gud.
Outside a certain particular boss, every enemy in the game dies fairly quickly. I'm going to give you a few pointers:
>Sword + enemy = red sticky ramen
Your sword isn't the "infinite ammo fallback" like other shooters. It's a tool, use it and use it frequently. Guns are for softening enemies at a distance. 80% of them WILL close-in on you (or pull you closer) and if you refuse to draw your sword to pull off the fancy moves you learned in Junior-Karate classes, you will be demon-chow.
>Shields
Plenty of enemies have these. Yes, you can break them. No it's not worth it. The man that attacks a castle wall will break his arms. Or in this case, your ammo count. Then you're needling some heavy with an Uzi because your revolver AND shotgun are hungry.
Have you noticed that dodge movement you can pull off? It's not for running away like chicken-at-market. It's for dashing around shields and hit them where the sun doesn't shine.
>Using Ki
Your spirit is as much, if not more, of a weapon as the rest of them. If you're constantly topped off on Ki, you're squandering a very important part of your tools. Blacksmith who hammers all day gets shitty cold sword.
>Disabling enemies
All the points above come together when you realize half the fight is about disabling enemies. Yes, killing them disables them, but you don't have a nuke in your pants (you have tiny bean pod). Half of your arsenal is about exposing enemies, stunlocking them or keeping them away. When 5 tall men approach, kick 4 in balls before challenging the 5th. Then you only have to kick 3 in balls before challenging the 4th.
tl,dr: You're dumping magazines in their faces while neglecting all the other tools you have. Of course they'll be bullet spongy.

Not if you bother to learn it. Every enemy can be weakened some way or another opening up some easy kills. But to do that, you need to do things other than "point at enemy, hold M1 for 5 minutes".
The second one is arguably bullet-spongy when you crank up the difficulty, but then the higher difficulty drops you some ridiculous loot in the first two levels and you proceed to wipe the floor with them. First couple of levels with no good weapons are hell though.
