RunALine is a free casual game developed by SkenonS Games for Android. The game features Liney, the main character, who has to navigate through obstacles to reach the finish line. What makes this game unique is that the faster you move, the longer Liney becomes, making it harder to avoid obstacles.

The game has two modes: campaign and survival. The campaign mode includes levels that get progressively harder and longer. On the other hand, the survival mode is an infinite game mode that gets harder the longer you play.

One of the best features of RunALine is the item shop, where you can customize Liney with hats, eyepieces, neckpieces, colors, and pets.

Overall, RunALine is a well-designed game that has been thoroughly playtested to ensure that it is possible to beat. If you're looking for a casual game with a unique twist, RunALine is definitely worth checking out.
