In Clockwiser the aim is to move the blocks on the left half of the screen to match it up with the right half of the screen. Starts off quite simple but soon requires a lot of thought - making it a very satisfying.
Improvements over the original include an incredibly handy Undo feature, and a new (optional) gesture-based control method to make moving the blocks around even easier. Plus there's no more need for passwords as the game saves each player's progress individually.
It contains the original 100 levels, the extra 10 levels from the MS-DOS version, and as an extra bonus, the 15 levels from the Amiga demo version. You also get a level editor thrown in, so you can make your own puzzles.
