ChangeReaction at Mac App Store analyse

ChangeReaction is a fast-paced puzzle game played with your ears, primarily intended for blind and low-vision gamers. Navigate the game board with the keyboard or supported game controller and build stacks of coins to rack up higher and higher scores! Match three coins of the same denomination vertically or horizontally to trigger a chain reaction that blows up all adjacent coins of the same value! ChangeReaction has no visual element; it's entirely played through an audio interface. Use your fingers, ears, and wits to rack up the highest scores possible! • Choose from three distinctly different variations of game play. • All game variations support three difficulty levels. • Play with the keyboard or supported game controller. • In ChangeReaction Classic, clear the board of all coins before time runs out! • In Loose Change, bombs continually explode, scattering the board's contents for added challenge! • In PayDay, try to keep the board from being cleared against all odds while racking up overtime by clearing board positions representing the hours of the work week. • Bonus rounds provide a chance to rack up even higher scores! • Exciting sounds and music. • Audio hints to help newcomers navigate the game and menus with their ears. • In app instructions and keyboard/game controller reference.
