It looks like you have to hold the direction for a bit prior to turning. Pretty bad UX in my opinion. Especially since this makes it nigh unplayable on mobile as you fat thumb the tiny D-pad trying to hold the right direction down.

I tried it on keyboard and it's a bit more playable, but frustrating for players like myself who more than have the dexterity to press exactly when I want to.

A+ for humour, artistic style, and concept... D for play-ability.
