Those little ladybug icons you'll be collecting as you run should both dictate the path you take and the lane you should stay in, but also add up so you can spend spend spend in the shop later. We've already mentioned how you should be spending that currency on power up upgrades and such, but the act of collecting them in the first place can guide you gently through the level. They're never in impossible to reach places, so watch for how they're placed and slide, swipe and jump to collect them all.
