Why keyboard controls remain useful
A keyboard gives repeatable directional input and keeps important actions under separate fingers. That can make a difference in lane-changing racers, grid strategy games, arena movement, platform timing, and puzzles where an accidental touch would select the wrong object. The games here state their keys on the public page instead of asking the player to discover them through trial and error.
Common layouts include arrow keys for movement, WASD as an alternative, Space or Enter for a primary action, and combinations that separate movement from firing or confirmation. A title may also support touch, but it appears in this collection because keyboard input is explicitly documented and can be used as a reliable desktop control method.
