At its core Hard Lines is a very simple game. You are a line (called Lionel) that, as tradition dictates, travels forward along its path. There are a few different control options but the default, and best, is swiping. To make your line turn just swipe a direction anywhere on the screen, it’s as easy as that. Your goal is simple, collect Glowy Things for points and don’t crash, you’ll die if you crash into the wall or another line trail but, as you would expect, if another line crashes into your trail you will kill them.
