Can you try updating the game and running it again? My theory is that you are in a country whose system defaults to using comma decimals, which would break my JSON loader. I added a fix for this and would like to know if it works!
Update: I ran into a new problem :(
The first 2 levels run fine, but after the 3rd one is loaded, the game crashes.
