I was just meaning, that if you think you can't do it in the timeframe, then you are making it too big for yourself. The rules are so loose that you could literally make a programming language that has a single command `run_my_awesome_game()` and fully impliment the logic etc in your language and library of choice. Obviously a trivial/useless example, but take it up a few notches and you could have something interesting. A DSL inside JSON can be very powerful.
