Stig

Here's an excerpt from Stig's Steam description:

Stig is a single-player puzzle game about finding a path through colors. The objective of the game is to walk on colored tiles in an order that matches a given pattern. As you progress through the levels, more and more mechanics are introduced, keeping the puzzle solving experience varied and fresh.

The controls in the game are simple. All you need in order to navigate the puzzles is to move up, down, left, and right. If you ever make a mistake there is an undo and a restart button as well, which might come in handy during some of the trickier levels.

The game does not require quick inputs or fast reaction times, and can be played at any pace.

The controls are simple. Core gameplay uses direction input (four directions) and an undo button. The game does not require multiple simultaneous inputs.

Controls for keyboard and gamepad can be remapped.
