This is my current status after 12h.
I have to say that I wasn’t expecting this theme. I got some ideas for every theme besides this one. But just like last time theme that won is the theme I’m least prepared for.

After two major crises. One caused by lack of sleep and second after hard battle with parsing JSON. This is what I have. Game is called “EVIL SOUL EATING DEMON LORD FROM HELL in HAPPY KINGDOM”. You are big bad demon in a happy good land and your goal is to do as much evil mayhem as possible. For that you get scores and for score you can buy more powerfull powers of destruction.
