You are DadHog, and all your hoglings are scattered in the yard. Unite all the hoglings, then bring them back to the Hogway!

Move DadHog by swiping in any direction. If you move into a space adjacent to a hogling (the white hedgehogs), you will stick to them. If a hogling touches another hogling, they will join the pack. 

If you want to get to the exit, you'll need to steer the family in the right direction. Tap the clockwise or counter-clockwise arrow buttons on the left side of the screen to rotate the whole bunch. Take note that you always rotate with DadHog as the axis. This will come into play in later levels. Tap the R button to restart the level. 

To complete a level, collect all the hoglings, then bring any one of your pack to the Hogway door.
