Every year, Tokyo Game Show is home to Sense of Wonder Night, a celebration of indie games. This year, one game managed to win the hearts of both the judges and the audience.
Albert Shih's "Museum of Simulation Technology" plays with forced perspective. By grabbing objects, players can change the size of objects in the world to solve puzzles. Other gameplay elements are slowly introduced, like the ability to rotate objects and portals--and yes, portals do make puzzle games better.
A work-in-progress version of Shih's game can be downloaded off his website.
