Thank you so much for playing my game!
The first idea was to put a fog or a camp in some areas to recover the flags, but then i thought it's a tiny game and it's not gonna work so much, so i put 4 flags, one to use it if you want in the tutorial, and three for each one area in the game. But you can handle as you want. Could use an indicator that helps the player to know about how many distance is far from the final too.
But thank you for your kind words, really appreciate it <3
