Hi Michelle; yes Reflexive do make games (all the Ricochet series was made by them as well as the Big Kahuna Reef games) though like most of the bigger Arcade developers they also sell most of the other developers games as well. You can see which games they actually developed themselves here:

IMO it's well worth getting, especially if you're into farm sims. The developer listened to the community when he first gave this away early last year. He went through over 20 revisons in a short space of time on the strength of comments made by the giveaway community. there's a Magic Farm ultimate being beta tested at this very moment, so I'd definitely hold off buying the original game until it's been released.
