Great game! I love that you can play any level and that there isn't a time limit, it makes for a very relaxing, enjoyable game. I think you should include more historical facts and such as intros to the levels! 5/5 game.
We initially wanted to design a game that help to relax and prevent the players from being stucked at one level for ever (you can skip the levels in the calendar). Adding more historical events sound like a good idea. They are fun to create and they add depth to the game. We are thinking of modifying existing levels and transform them into Leonardo Da Vinci levels in an upcoming release. Thanks for the suggestion.
