Oh, that explains a lot. During the walkthrough, I simply didn't realize that you can hit at different angles. Honestly, when you control the mouse, I don't want to speak for everyone, but I'll speak for myself - it's convenient to choose your attack direction based on where the cursor is pointing, rather than by pressing buttons on the keyboard. I realize that this doesn't apply to all players and that similar attack mechanics exist even in such famous games as cup head. But honestly, for me it was so inconvenient even there that I went through the game until the very end just ignoring the aiming angles with auto guided shooting. The simple point is that cup head provided me with an analog and this game didn't and so even when I realized that you could select an angle, it though got a lot better, it still wasn't convenient. Perhaps individual preference. But I'll definitely up the grade now that I know about the pointing angle.
