Should be playable as of this PR. Someone confirm?

In latest build it playable but don't set game hard mode because some controlls in battle are not useable like purge and will make game very hard even on easy.

Developer Jarves implemented Sixaxis support for DS4... So I guess that would work for some people.

However it turns out that the world map screen (and possibly more) has like a 75 % chance to crash upon loading into a location, so not really playable either way.
