Yes. You can only play and unlock a door if you have enough keys. Run out and wait or buy them. I would like to think that its a strategy/puzzle game so that as long as you are clever enough to complete the levels you can continue. But then I remember its a free to play and realize there is bound to be a level I get to that I will have to pay.
For now I will see how far I can get. I was going to suggest to those of you that like the look of this to try Rooms The Main Building which was out on DS and iOS a few years ago to go and download that but it seems it was pulled :/
