Trick or Treat is a small python game, where we have to dodge enemies and each dodge is counted.

Let's see if we can find a winning condition in the source code: I guessed we have to survive long enough or dodge enough enemies. So we need something like if someVariable > someMagicNumber and actually, in the game_loop, there is a condition if gf > (5 * 20): and gf seems to be incremented from time to time.

If the condition holds, we have game.pause_text = gs(). So let's just put this line as the first instruction inside game_loop and it is triggered right from the beginning.

Turns out: This really is the line of code responsible to print the flag. Solved.
