Portal was about using physics to your advantage. TesserAct, a puzzle platformer from Phoenix-based Propelled Bird Software, lets you bend it to your will, lead developer Clay Walters said in an interview with Arizona Gamer.
The game is set in a “universe based on scientific theory,” Walters said. It follows Sam, a student who is inexplicably teleported to an abandoned moon base in another dimension.
She stumbles upon the Catalyst, a tool that can manipulate the laws of physics, and sets out to find a way back home.
