After looking at the gameplay I'm thinking: touch left to turn left, touch right to turn right, touch both to brake. I hope that maintains the chaotic fun of this game though.
Is there a subreddit we can use to follow development?
Edit: I remember Flail Rider which had a similar isometric view but very different gameplay. You could use that for inspiration.
A course mate of mine made this.
