I played the windows version of this via the posted link and had a little go with the game. I think you did really well getting something a first game together which can be hard to do in a week when you're learning! I would say that I am not too certain how the theme is implemented to your game, other than the restarting level feature which will often be present in level based games anyway. It's a good start to your journey though and I hope you enjoyed the process of making a game :)
