It uses the second analog to pan the camera vertically. It's not critical, but sometimes you will want to look around before you jump off a ledge.

It's a melee oriented Metroidvania. Think Ori And The Blind Forest but with more insects and inexplicable frilly faux-Victorian edifices, and less pokey combat. You could play it on a SNES pad if you wanted to. I got to 100% on it back when using a cheap wireless keyboard from my couch.

I don't know about you, but Hollow Knight's main contribution to my household is that my wife and I still call any filigree wrought ironwork benches we see "save points."

Yeah, bind two to up/down on rstick and you'll have plenty

both sticks

no

1 sticks 8 buttons

yep, actually I use 9 keys but one of those is quick cast which really good for quick combat but it's not actually needed since you have the same thing on the regular spell button, just a tad bit slower

You can do it without analog stick iirc, it's very much designed for dpad.

If it will be like the first it won't be a wall of difficulty checks thrown in your way. What I liked most of Hollow Knight it was how masterly designed it was. It took you by your hand and thought every skill check you needed beforehand. You got good as you progressed. It it not frustrating as Dark Souls, it has a curve that kept increasing.

Use the keyboard like a real gamer.
