Short and simple. Not much of a challenge, just gathering and basic things like item combining and placement. The game is about a minute long, but it is part of a series so I'll give it a little leniency there. One thing that bothered me was that the hay was referred to as "hair," which most prehistoric creatures didn't have. A select few dinos were believed to have hair, and their species were up in cold places like Siberia, not near a volcano.
