Here's the new version in action:
You can try or buy Angry Birds here in the Windows Phone Store. You don't, surely, need more comment here by now? I have to confess to getting stuck somewhere in the middle of Angry Birds several times and thus never likely to even see the new levels. Not enough imagination from me? Dexterity or eyesight not up to scratch?
Classic gaming, anyway - how far have you got in the original?
