Hello, thank you for trying my game! I must admit that the recognition algorithm is not nearly as refined as Google's is, which probably contributed to some of the frustration. Also, I should have clarified that it can only recognize very simple doodles (in the case of the sea turtle, 6 appropriately sized circles should do the trick). This is technology that I was interested in prior to the jam, and I was sort of experimenting to see if it could be implemented in a game. Maybe with a better algorithm or approach something is possible, but it seems in this case it's not quite there. Thanks again!
