Well, what can be written about the gameplay that hasn't already been written? That's right. Nothing. This is still the same great game it always was, so I guess the only question left is... 'how does it play with touch screen controls?'
The answer is... sometimes better, sometimes worse. The game offers point and move and on screen d-pad control methods, but frankly I've found that neither are good for all situations. Some screens are better on touch, others (that require more precise movement) are better on dpad. In a world, it's a bit hit and miss, and gets frustrating.
The game is still amazing fun to play, and the HD/Low Res options are a nice touch, however I can only recommend this if it's on offer (as it was when I purchased it) unless you really loved the original game (and who didn't?)
