Seems like the controls are the same as the original!

Use the Shift key to pick up the sword. And I think Space to attack and the Up cursor key to block when you get to the swordsman.

Slash sword is the middle tap. Took me awhile to figure that out but makes sense now that I know since you can't slash backwards.

How do you walk forward slowly? Tapping bottom edges does “run” action for me.

Edit: figured it out, tap on the center and swipe to the left/right to walk.

Interesting. Only the four direction buttons work for me, regardless of num lock setting. eg 2, 4, 6, 8. None of the corner buttons nor middle button have any kind of effect.

This is when using Firefox on Linux, and using a standard 101-key external keyboard.

Hm, I couldn’t get it to work on my iPhone (not that I actually expected it to) - I could do some things but the controls didn’t seem to work consistently.
