One More Line

One More Line is an endless game, scrolling horizontally or vertically based on the platform, with a slingshot game mechanic. The player controls an object that travels at a constant speed, leaving behind a coloured trail. The goal of the game is to get as far in the environment as possible. There are various objects that need to be avoided. By tapping or clicking, and holding, the player's object is attached to the nearest object and then moves around it in a perfect circle until released, launching it. The distance to the object before attachment determines the rotation speed and diameter. Using the slingshot mechanic it is possible to travel further down the level by changing the movement direction.

In addition to the objects in the environment, it is also not allowed to touch the walls, but while in a slingshot rotation the object is allowed to travel through them. A single collision immediately ends the game. This also happens when the player's object collides when another object while in rotation. The game keeps track of the best scores.

The mobile and Windows Apps version are all free-to-play with a single in-app purchase to remove the in-game advertisements. The browser version does not have advertisements, but promotes the mobile version prominently. The later released PC version has some exclusive features: local multiplayer for up to four players, several types of hats, unlockable tails and several skins. It is a commercial release and does not contain advertisements.
