I'm amazed at how quickly Ron Gilbert's latest game is falling in price - six months and already just shy of £3. This adventure/platforming oddity (from the minds behind Monkey Island) is funny and cerebral, but a huge amount of repetition and padding is built directly into the experience. For the price, it's difficult to care. UPDATE: Credit to greysquaill at HotUKDeals, who found this before we did.
