The game we keep mutating.

It started with just a small blue bird reminiscent of Twitter’s mascot or Angry Birds, a little icon you had to simply move with the four arrow keys to the exit in the lower-right corner of the screen. But the real goal of the game “please be nice :(“ was to be the first person to finish it, because, as we reported back in March, that meant you got suggest a feature. And then creators Aran Koning and Herman Groenenboom added it in.

The first suggestion was to add a character selection screen with more options for your protagonist, including female choices. Next came the idea to make the player feel “Love” — which brought another bird with hearts floating above it chasing after you. The next victor wanted a background with flashy colors. In the first week Nice went through 40 iterations. Since the game launched in March, it has been modified and modified up to version 133.

Koning and Groenenboom are computer science students in Utrecht, in the Netherlands. Koning said, “Please be nice was inspired by TwitchPlaysPokemon, but instead of people working together in an anarchic way to beat a game, they make a game instead.”
