Thank you all for your support on the subject, and apologies for taking time to answer. We have actually finished the contract and the developer was paid fully, so I do not think there is any legal issues (my mistake for not pointing that out). From the developers point of view, the game is ready for launch but we see a lot of flaws in the animations, art and sounds. We have already contacted an amazing animator and he is working with us right now. The development company didn't like that we are outsourcing the animator, so they are making it hard for us to continue with a new contract and fix the problems. That is why we want to transfer the project to another team. Our question is do we only need the source files? will that be enough for the new company to start on fixing the project? or is it easier and more efficient to start from scratch?
