how do you play with a phone? i can only swipe tiles but I cant change dimension. there need to be some sort of "two finger swipe" for WASD keys.

I couldn't work out how to implement the extra 2 movement dimensions on a phone. Does JS support detecting 2 finger swipes (or something similar) in a sane way?

You can certainly grab the number of touches in an event - two-finger swipe might be interesting. MDN has quite a few examples: https://developer.mozilla.org/en-US/docs/Web/Guide/Events/To...

Very cool, thanks; I've added two-finger swipe for the extra two dimensions.

You could separate the screen. Top half/bottom half.
