Thanks! Yes it's a little more awkward than I'd have liked for new players. Maybe I can do some improvements once the jam results are in.
The red lines are supposed to flick up as they represent roughly where your skates would be on the ground. No reason why I can't make them go dead horizontal. Or flick down instead might make them feel more like the actual action, even if it's not strictly accurate. (The blue swipe left/right sometimes gives false positives as well)
