"I don't think Joe Danger Touch feels like anything else I've played," Hello Games managing director Sean Murray said. "I want it to feel like it could only work on iOS, because we've built it specifically for the device. Towards the end of the game, it gets super difficult, probably more so than the console version. I'm amazed what levels I can handle sometimes, and the subtlety possible with just a touch interface."
That touch interface sees players swiping to make Joe wheelie, flicking to knock obstacles off the track, tapping to jump, and holding down to crouch. Presumably you have to blow on the screen to put him out following the inevitable ring of fire mishap.
