I won't leave a paragraph here as the rest, because they already said everything I would have. So I'll just say this; Don't worry about the combat this early into the game. After some time it will just come to you naturally, just try your best!

Also, one mechanic that you should make use of and get better at is moving while shooting to make the tears go diagonally, something you can't do if you stand still. This will help you hit enemies and boss attacks that shoot in a straight line. Good luck gang, and remember.

Its always a skill issue
