I recently upgraded to the new retina iPad and discovered that one of my all time favorite apps, PuzzleManiak HD now runs so slowly that it is unusable. It appears as though the app is dead and the developer is nowhere to be found as the last update was a year ago. So, I am looking for a new puzzle game to keep me occupied. I really liked the fact that there were multiple different types of puzzles in puzzlemaniak (esp. bridges, lights out, slant, and pattern) and I really liked the fact that the puzzles were always randomly generated, so it gave me a nice opportunity to play for scores (time). Any thoughts or suggestions?
