Notpron is an online puzzle game created in 2004 by German game developer David Munnich. Notpron has a total of 140 levels, ranging from 82 positive levels, 44 harmful levels, and 14 Greek levels (Ranging from Alpha to Nu). These three groups of levels do not differ from each other, apart from them being named differently than the others. From a game design standpoint the main idea behind Notpron is that it’s doing one thing different from all other games,” Münnich says from his home in Saarbrücken, Germany. “Usually you start a game, and the game tells you what to do, and you have to act inside that system. Notpron, however, expects you to work around the system, without even saying you to do so.
