I built this game in late 2013 using the Starling Framework. I wanted to make a memory game that used swipe gestures, and came up with this concept: You are a wizard and kill monsters by casting specific spells that only kill monsters of that type. To cast a spell, you swipe your finger in the directions indicated. Each new monster introduced means you need to learn one more spell. It gets pretty hard!
Remember, this was designed for mobile, so to simulate a swipe, you must click the mouse, drag it to a direction, then release.
