This is really great! It did take me a bit of time to find that you could possess pieces. I also had to skip to a later level to find that snakes move diagonal and the knights vertical and horizontal becuase I just happened to guess right with the first 2 easier levels that teach you this so I didn't take any of that information in. Everything else is pretty much one core idea, executed to perfection. Best of luck with this game, great job!
