Voodoo Dice is relatively cheap weighing in at 800 MSPs, and there is enough here to keep you going for a couple of hours. The question really is, will you want to play it for that long? The answer is probably not.
All in all, the time I spent playing this game I enjoyed, especially the more challenging levels that required a bit of thinking to finish. However at 800 MS points it's hard to justify spending that much when there are so many better games out there.
