Such a great game! I really enjoyed this and it brought me back to when I was a kid and loved trying to do shadow puppets with my hands. The game worked smoothly and the levels progressively got more difficult, would love to try out even more levels :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
