Regardless of whether Chillingo releases additional content, Food Processing is a quality game worth your hard-earned cash, if for nothing else than a little stress relief. That pumpkin never had a chance.
Overall it is a good game. The production levels are high, and I like it as a 'simple idea done well'. I would love to have seen a bit more though; perhaps some more unlockables, different food items, secret bonuses or something.
