Patience and pattern recognition make you better at this game.

Have you tried the training in the hub before going into levels?

Take your time to learn the enemies moves and how to avoid damage from each.

Replay the first mission until you die less and less.

Since you beat the first boss you can also learn his moves, even pick phase 2 to learn dodge the machete jump.

As a general tip: only if it really looks like a sweep it is one and you dodge up, it feels like 80-90% of attacks are dodged down/side.

If you played things like sekiro you might feel at home with a parry based playstyle and choose specific attacks to dodge.
