Narbacular Drop is an indie puzzle-platform game developed by the student team at DigiPen Institute of Technology in 2004. It is the game that inspired the popular Portal series of games. In Narbacular Drop, the player controls a princess who must solve puzzles by manipulating two portals - one blue and one orange. The portals can be used to move objects around the game world, change the environment and interact with various objects. The game features physics-based puzzles, as well as using special items and environmental elements to progress through levels. The game boasts a unique graphical style and a strong emphasis on physics. Narbacular Drop is an innovative and entertaining game with a lot of replayability.
