Stefan Preuss has introduced AcChen 1.0 for Mac OS X. It’s a “find the matching tile” type of game.
Here’s how it’s described: “Clear the board by finding two items with identical symbols. Master the 60 different levels and 12 bonus maps in the single player campaign. Every 5th level you play is a bonus level. Unlock new levels by beating the clock or play in ‘chill mode’ without any pressure: no timer, no score just happy tile hunting.”
AcChen requires Mac OS X 10.8 or later. It costs US$2.99 and is available worldwide exclusively through the Mac App Store in the Games category. Go to http://miscstuff.de for more info.
